Le funzionalità base di Code_Saturne permettono la gestione di flussi sia incomprimibili sia espandibili con o senza trasferimento di calore e turbolenza. Sono disponibili moduli dedicati per fenomeni fisici specifici come trasferimento di calore per radiazione, combustione (gas, carbone, olio combustibile pesante, ...), magneto-idrodinamica, flussi comprimibili, flussi a due fasi (approccio di Eulero-Lagrange con accoppiamento a due vie), estensioni per applicazioni specifiche (es.: Mercure_Saturne per ambienti atmosferici).

Funziona in parallelo con MPI su macchine con memoria distribuita. Sviluppato a partire dal 1997 al dipartimento di Ricerca e sviluppo dell'EDF, si basa su un approccio "co-located" a volumi finiti che accetta griglie con qualsiasi tipo di cella (tetraedri, esaedri, prismi, piramidi, poliedri...) e qualsiasi tipo di struttura della griglia (non strutturata, a blocchi, ibrida, conforme o con nodi incompleti, ...).

Questo pacchetto contiene i file binari.

GAP è un sistema di algebra computazionale discreta con particolare enfasi sulla teoria dei gruppi computazionale. GAP fornisce un linguaggio di programmazione, una libreria di migliaia di funzioni che implementano algoritmi algebrici scritti nel linguaggio GAP ed anche vaste librerie di dati con oggetti algebrici. GAP è usato nella ricerca e nell'insegnamento per lo studio dei gruppi e delle loro rappresentazioni, degli anelli, spazi vettoriali, algebre, strutture combinatorie ed altro.

Questo pacchetto il compilatore GAP e i file header e oggetto necessari per compilare i pacchetti GAP.

Il compilatore GAP (GAC) crea codice C a partire da codice GAP e successivamente richiama il compilatore C di sistema per produrre il codice macchina. Questa può essere una velocizzazione.

La libreria JEL permette agli utenti di inserire espressioni algebriche nei propri programmi. Dato che JEL converte le espressioni direttamente in bytecode Java, velocizza in modo significativo il loro tempo di valutazione. Se la macchina virtuale Java dell'utente ha un compilatore JIT le espressioni vengono compilate in modo trasparente in codice macchina nativo.

JEL può essere uno strumento molto utile per una varietà di applicazioni in ambito scientifico che comportano funzioni definite dall'utente, ad esempio per creare grafici, per applicare fit a insiemi di dati e per risolvere integrali o equazioni differenziali. Un altro importante caso d'uso per JEL sono le operazioni algebriche tra due o più colonne di una tabella di database.

ANN è una libreria scritta in C++ che gestisce strutture di dati ed algoritmi per la ricerca dei primi vicini sia esatta sia approssimata in un numero di dimensioni arbitrariamente grande. ANN assume che le distanze siano misurate usando una qualsiasi classe di funzioni di distanza dette metriche Minkowski. Queste includono la ben nota distanza euclidea, la distanza Manhattan e la distanza massima. Le prestazioni di ANN sono piuttosto efficienti per insiemi di punti che variano in numero dalle migliaia alle centinaia di migliaia, e fino a 20 dimensioni.

Questo pacchetto contiene i file header per sviluppare applicazioni con la libreria ANN.

Il software ARPACK è in grado di risolvere problemi agli autovalori a larga scala simmetrici, non simmetrici e generalizzati a partire da aree di applicazione significative. Il software è progettato per calcolare alcuni (k) autovalori con caratteristiche specificate dall'utente, come quelli con la parte reale più grande o la più grande magnitudine. I requisiti di archiviazione sono dell'ordine di n*k posizioni; non è necessario spazio di archiviazione aggiuntivo. Per l'autospazio a k dimensioni desiderato viene calcolato un insieme di vettori di Schur che è numericamente ortogonale alla precisione di lavoro. A richiesta sono disponibili autovettori numericamente accurati.

Questo pacchetto contiene le librerie statiche e la documentazione per fare sviluppo con libarpack (inclusi esempi).

Questo pacchetto è un aggiornamento binario incompatibile al pacchetto blas-dev. Sono state incorporate svariate modifiche secondarie all'interfaccia C.

BLAS (Basic Linear Algebra Subroutines) è un insieme di procedure efficienti per la maggior parte delle operazioni di base su matrici e vettori. È ampiamente usato come base per altri software di algebra lineare di qualità elevata, per esempio lapack e linpack. Questa implementazione è quella di riferimento per Fortran 77 che si trova dentro netlib.

Questo pacchetto contiene una versione statica della libreria.

BLIS is a portable software framework for instantiating high-performance BLAS-like dense linear algebra libraries. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations. BLIS is written in ISO C99 and available under a new/modified/3-clause BSD license. While BLIS exports a new BLAS-like API, it also includes a BLAS compatibility layer which gives application developers access to BLIS implementations via traditional BLAS routine calls. An object-based API is also available for more experienced users.

The package pulls development files for one of the 32-bit variants.

Minpack includes software for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix or directly from the problem functions. The paths include facilities for systems of equations with a banded Jacobian matrix, for least squares problems with a large amount of data, and for checking the consistency of the Jacobian matrix with the functions.

This is the C re-write of the original fortran minpack implementation.

This package contains development files needed to build cminpack applications.

Neartree is an API and a library for finding nearest neighbors among points in spaces of arbitrary dimensions. This package provides a C++ template, TNear.h, and C library and header files for compiling programs using Neartree.

The library uses the Nearest Neighbor algorithm after Kalantari and McDonald, (IEEE Transactions on Software Engineering, v. SE-9, pp. 631-634,1983) modified to use recursion instead of a double-linked tree and simplified so that it does less checking for things like is the distance to the right less than the distance to the left; it was found that these checks make little to no difference.

FreeFem++ è un'implementazione di un linguaggio dedicato al metodo degli elementi finiti. Permette di risolvere facilmente le equazioni differenziali alle derivate parziali (PDE).

I problemi che coinvolgono le PDE da svariate branche della fisica, come le interazioni delle strutture fluide, richiedono l'interpolazione di dati su diversi reticoli e la loro manipolazione per mezzo di un unico programma. FreeFem++ include un veloce algoritmo di interpolazione basato su quadtree e un linguaggio di manipolazione di tali dati su reticoli multipli. Contiene anche un potente generatore e strumento di adattamento di reticoli integrato in modo perfetto in FreeFem++, chiamato bamg.

FreeFem++ è scritto in C++ ed il linguaggio FreeFem++ è un idioma del C++ che permette una curva di apprendimento agevole.

Questo pacchetto contiene i file di sviluppo di FreeFem++.

This is not a full linear algebra library, only a GEMM library: it only does general matrix multiplication ("GEMM").

Its performance goals differ from typical GEMM performance goals in the following ways: 1. It cares not only about speed, but also about minimizing power usage.

   It specifically cares about charge usage in mobile/embedded devices.
2. Most GEMMs are optimized primarily for large dense matrix sizes (>= 1000).
   It does care about large sizes, but it also cares specifically about the
   typically smaller matrix sizes encountered in various mobile applications.

Keep in mind (previous section) that gemmlowp itself is a pure-headers-only library.

Givaro is a C++ library for arithmetic and algebraic computations. Its main features are implementations of the basic arithmetic of many mathematical entities: Primes fields, Extensions Fields, Finite Fields, Finite Rings, Polynomials, Algebraic numbers, and Arbitrary precision integers and rationals (C++ wrappers over gmp).

Givaro also provides data-structures and templated classes for the manipulation of basic algebraic objects, such as vectors, matrices (dense, sparse, structured), univariate polynomials (and therefore recursive multivariate).

It contains different program modules and is fully compatible with the LinBox linear algebra library and the Athapascan environment, which permits parallel programming.

This package contains development files for Givaro.

This interface allows gnuplot to be controlled from C++ and is designed to be the lowest hanging fruit. In other words, if you know how gnuplot works it should only take 30 seconds to learn this library. Basically it is just an iostream pipe to gnuplot with some extra functions for pushing data arrays and getting mouse clicks. Data sources include STL containers (eg. vector or map) and one or two dimensional Blitz++ arrays (of scalars or TinyVectors). Support for other data sources should be easy to add.

Basically there are two functions defined: send() sends arrays of data values (it is overloaded to do the right thing based upon what type of variable you pass) and getMouse() gets the position of a mouse click. Everything else is accomplished by sending commands manually to gnuplot via the iostream interface.

IML is a library for exact, dense linear algebra over the integers. IML contains algorithms for nonsingular rational system solving, computing the right nullspace of an integer matrix, and certified linear system solving.

In addition, IML provides some low level routines for a variety of mod p matrix operations: computing the row-echelon form, determinant, rank profile, and inverse of a mod p matrix. These mod p routines are not general purpose; they require that p satisfy some preconditions based on the dimension of the input matrix (usually p should be prime and should be no more than about 20 bits long).

This package contains development files for IML.

ITSOL is a library of iterative solvers for general sparse linear systems of equations. ITSOL can be viewed as an extension of the itsol module in SPARSKIT. It is written in C and offers a selection of recently developed preconditioners. The preconditioner suite includes:

  • ILUK (ILU preconditioner with level of fill)
  • ILUT (ILU preconditioner with threshold)
  • ILUC (Crout version of ILUT)
  • VBILUK (variable block preconditioner with level of fill - with automatic block detection)
  • VBILUT (variable block preconditioner with threshold - with automatic block detection)
  • ARMS (Algebraic Recursive Multilevel Solvers -- includes actually several methods - In particular the standard ARMS and the ddPQ version which uses nonsymmetric permutations)

Note that ITSOL is a scalar package. You may find parallel implementations of some of the preconditioners listed above in pARMS.

This package provides the itsol header files required to compile C/C++ programs that use ITSOL.

JAMA/C++ was adapted for The Template Numerical Toolkit (TNT) from JAMA, a Java Matrix Library, developed jointly by the Mathworks and NIST. See http://math.nist.gov/javanumerics/jama for more information.

TNT is a collection of interfaces and reference implementations of numerical objects useful for scientific computing in C++. The toolkit defines interfaces for basic data structures, such as multidimensional arrays and sparse matrices, commonly used in numerical applications. The goal of this package is to provide reusable software components that address many of the portability and maintenance problems with C++ codes.

TNT provides a distinction between interfaces and implementations of TNT components. For example, there is a TNT interface for two-dimensional arrays which describes how individual elements are accessed and how certain information, such as the array dimensions, can be used in algorithms; however, there can be several implementations of such an interface: one that uses expression templates, or one that uses BLAS kernels, or another that is instrumented to provide debugging information. By specifying only the interface, applications codes may utilize such algorithms, while giving library developers the greatest flexibility in employing optimization or portability strategies.

Lip interpolates scattered multivariate data with a Lipschitz function.

Methods of interpolation of multivariate scattered data are scarce. The programming library Lip implements a new method by G. Beliakov, which relies on building reliable lower and upper approximations of Lipschitz functions. If we assume that the function that we want to interpolate is Lipschitz-continuous, we can provide tight bounds on its values at any point, in the worse case scenario. Thus we obtain the interpolant, which approximates the unknown Lipschitz function f best in the worst case scenario. This translates into reliable learning of f, something that other methods cannot do (the error of approximation of most other methods can be infinitely large, depending on what f generated the data).

Lipschitz condition implies that the rate of change of the function is bounded:

|f(x)-f(y)|<M||x-y||.

It is easily interpreted as the largest slope of the function f. f needs not be differentiable.

The interpolant based on the Lipschitz properties of the function is piecewise linear, it possesses many useful properties, and it is shown that it is the best possible approximation to f in the worst case scenario. The value of the interpolant depends on the data points in the immediate neigbourhood of the point in question, and in this sense, the method is similar to the natural neighbour interpolation.

There are two methods of construction and evaluation of the interpolant. The explicit method processes all data points to find the neighbours of the point in question. It does not require any preprocessing, but the evaluation of the interpolant has linear complexity O(K) in terms of the number of data.

"Fast" method requires substantial preprocessing in the case of more than 3-4 variables, but then it provides O(log K) evaluation time, and thus is suitable for very large data sets (K of order of 500000) and modest dimension (n=1-4). For larger dimension, explicit method becomes practically more efficient. The class library Lip implements both fast and explicit methods.

This package contains the development files (headers, so and static libraries) for MAdLib.

MAdLib is a library that performs global node repositioning and mesh adaptation by local mesh modifications on tetrahedral or triangular meshes. It is designed to frequently adapt the mesh in transient computations. MAdLib is written in C++.

The adaptation procedure is driven by two objectives:

  • make the edge lengths as close as possible to a (non-homogenous)

    prescribed length,

  • maintain a satisfying element quality everywhere.

MAdLib can be used in transient computations in order to maintain a satisfying element quality (moving boundaries, multiphase flows with interface tracking, ...) or/and to apply selective refinements and coarsenings (error estimators based, interface capturing: shocks, free surfaces, ...).

This package provides a C library of functions for interval arithmetic computations with arbitrary precision.

The basic principle of interval arithmetic consists in enclosing every number by an interval containing it and being representable by machine numbers: for instance it can be stored as its lower and upper endpoints and these bounds are machine numbers, or as a centre and a radius which are machine numbers.

The arithmetic operations are extended for interval operands in such a way that the exact result of the operation belongs to the computed interval.

The purpose of an arbitrary precision interval arithmetic is on the one hand to get guaranteed results, thanks to interval computation, and on the other hand to obtain accurate results, thanks to multiple precision arithmetic. The MPFI library is built upon MPFR in order to benefit from the correct roundings provided by MPFR. Further advantages of using MPFR are its portability and compliance with the IEEE 754 standard for floating-point arithmetic.

This package provides the static library and symbolic links needed for development.

MPFR C++ introduces C++ arbitrary precision numeric types; based on GNU MPFR --- Multiple Precision Floating-Point Reliable Library.

MPFR C++ makes possible to use MPFR calculations in the same simple way as calculations with numbers of built-in types double or float: all arithmetic and boolean operators (+, -, *, /, >, !=, etc.) are implemented through operator overloading technique; elementary mathematical functions (sqrt, pow, sin, cos, etc.) are supported.

OpenTURNS è uno strumento potente e universale per trattare e quantificare incertezze in simulazioni numeriche per progettazione, ottimizzazione e controllo. Permette studi analitici sia di sensibilità sia di affidabilità:

  • definire l'output di interesse e i criteri di decisione;
  • quantificare e creare modelli per la fonte di incertezza;
  • propagare incertezze o analizzare la sensibilità e
  • classificare le fonti di incertezza.

OenTURNS è un vasto progetto con più di 300 classi C++, che usa software rinomato e ben supportato, come R per i metodi statistici e BLAS/LAPACK per l'algebra lineare.

Questo pacchetto fornisce gli header di OpenTURNS che si dovrebbero utilizzare se si vuole collegare la propria applicazione alla libreria.

QUADRULE è una libreria C che fornisce varie formule di quadratura utilizzate per approssimare l'integrale di una funzione su diversi domini.

QUADRULE restituisce l'ascissa e il peso di diverse formule di quadratura ad una dimensione per l'approssimazione dell'integrale di una funzione. Generalmente la migliore formula è la quadratura di Gauss-Legendre, ma altre formule offrono funzionalità speciali che includono la capacità di gestire alcune funzioni peso, approssimare un integrale in una regione di integrazione infinita, oppure stimare l'errore di approssimazione.

Questo pacchetto fornisce tutto il necessario per compilare programmi C che chiamano funzioni di quadrule.

RanLip genera variabili casuali con densità multivariabile di Lipschitz arbitraria.

Mentre la generazione di numeri casuali da una grande varietà di distribuzioni è implementata in molti pacchetti (come la libreria GSL http://www.gnu.org/software/gsl/ e la libreria UNURAN http://statistik.wu-wien.ac.at/unuran/), la generazione di variabili casuali con una distribuzione arbitraria, in particolare se multivariabile, è un'operazione per niente banale. RanLip è un metodo per la generazione di variabili casuali con densità di Lipschitz continua e arbitraria che funziona sia con una sia con più variabili, se la dimensione non è troppo grande (da 3 a 10 variabili).

La condizione di Lipschitz implica che l'incremento della funzione (in questo caso la densità di probabilità p(x)) sia limitata:

|p(x)-p(y)|<M||x-y||

Da questa condizione si può costruire una stima per eccesso della densità, la cosiddetta funzione cappello h(x)>=p(x), usando i valori di p(x) in alcuni punti. Più valori si usano e migliore sarà la funzione cappello. Il metodo di accettazione/rifiuto funziona così: si genera una variabile X con densità h(x); si genera un numero casuale Z indipendente uniforme su (0,1); se p(X)<=Zh(x) allora si restituisce X altrimenti di ripetono tutti i passi precedenti.

RanLip costruisce una funzione cappello costante a tratti della funzione di densità p(x) richiesta suddividendo il dominio di p (un rettangolo n-dimensionale) in molti rettangoli più piccoli, calcolando il limite superiore di p(x) in ognuno di questi rettangoli e usando tale limite superiore come valore della funzione cappello.

Files provided by this package are required to develop new programs with the Scythe library. There is no binary library associated with these headers, i.e. all template code is contained within and no further dependencies are required at runtime

The Scythe Statistical Library is an open source C++ library for statistical computation. It includes a suite of matrix manipulation functions, a suite of pseudo-random number generators, and a suite of numerical optimizers. Programs written using Scythe are generally much faster than those written in commonly used interpreted languages, such as R, Matlab, and GAUSS; and can be compiled on any system with the GNU GCC compiler (and perhaps with other C++ compilers). One of the primary design goals of the Scythe developers has been ease of use for non-expert C++ programmers. Ease of use is provided through three primary mechanisms: (1) operator and function over-loading, (2) numerous pre-fabricated utility functions, and (3) clear documentation and example programs. Additionally, Scythe is quite flexible and entirely extensible because the source code is available to all users.

Development files for SuperLU.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines.

The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

This package contains the header and development files to build against SuperLU.

Tachyon è un sistema di ray tracing in parallelo, portabile e ad alte prestazioni, che supporta implementazioni MPI e multi-thread. Tachyon è compilato come libreria C richiamabile che può essere usata con i programmi d'esempio forniti o con le proprie applicazioni. Il rilascio include anche un semplice frontend per analizzatore di file di scenari che legge diversi tipi di formato.

Tachyon implementa tutte le primitive geometriche di base, come triangoli, piani, sfere, cilindri, ecc. Alcuni degli obiettivi nello sviluppo di Tachyon erano di renderlo veloce e di far sì che lavorasse bene in parallelo. Questo è ciò che lo distingue da programmi più ricchi di funzionalità come POV-Ray, Rayshade e altri. Tachyon supporta abbastanza funzionalità da essere un'alternativa eccellente per programmi più lenti per compiti di animazione e visualizzazione scientifica complessi. Col tempo Tachyon incorporerà di certo ulteriori funzionalità, ma continuando a fare attenzione alle prestazioni di rendering.

The package is enhanced by the following packages: tachyon-doc

The Template Numerical Toolkit (TNT) is a collection of interfaces and reference implementations of numerical objects useful for scientific computing in C++. The toolkit defines interfaces for basic data structures, such as multidimensional arrays and sparse matrices, commonly used in numerical applications. The goal of this package is to provide reusable software components that address many of the portability and maintenance problems with C++ codes.

TNT provides a distinction between interfaces and implementations of TNT components. For example, there is a TNT interface for two-dimensional arrays which describes how individual elements are accessed and how certain information, such as the array dimensions, can be used in algorithms; however, there can be several implementations of such an interface: one that uses expression templates, or one that uses BLAS kernels, or another that is instrumented to provide debugging information. By specifying only the interface, applications codes may utilize such algorithms, while giving library developers the greatest flexibility in employing optimization or portability strategies.

UG is a flexible software tool for the numerical solution of partial differential equations on unstructured meshes, with a focus on multigrid methods. It has a very powerful grid manager, which supports two- and three-dimensional grids with mixed element types. The grids can be adaptively refinement using either classic red/green-refinement, or pure red refinement with hanging nodes. All this is fully parallelized and can run on large distributed machines.

The version in this package has been built with the necessary flags for use with the Dune software system.

This package contains the development files.

ASTEVAL is a safe(ish) evaluator of Python expressions and statements, using Python's ast module. The idea is to provide a simple, safe, and robust miniature mathematical language that can handle user-input. The emphasis here is on mathematical expressions, and so many functions from numpy are imported and used if available.

Many Python lanquage constructs are supported by default, These include slicing, subscripting, list comprehension, conditionals (if-elif-else blocks and if expressions), flow control (for loops, while loops, and try-except-finally blocks). All data are Python objects, and built-in data structures (dictionaries, tuple, lists, numpy arrays, strings) are fully supported by default.

Many of the standard builtin Python functions are available, as are all mathemetical functions from the math module. If the numpy module is installed, many of its functions will also be available. Users can define and run their own functions within the confines of the limitations of asteval.

There are several absences and differences with Python, and asteval is by no means an attempt to reproduce Python with its own ast module. Some of the most important differences and absences are:

  • Variable and function symbol names are held in a simple symbol table (a single dictionary), giving a flat namespace.
  • creating classes is not supported.
  • importing modules is not supported.
  • function decorators, yield, lambda, exec, and eval are not supported.
  • files can only be opened in read-only mode.

In addition, accessing many internal methods and classes of objects is forbidden in order to strengthen asteval against malicious user code. .

This package installs the library for Python 3.

The core of BRiAl is a C++ library, which provides high-level data types for Boolean polynomials and monomials, exponent vectors, as well as for the underlying polynomial rings and subsets of the powerset of the Boolean variables. As a unique approach, binary decision diagrams are used as internal storage type for polynomial structures. On top of this C++-library a Python interface is provided. This allows parsing of complex polynomial systems, as well as sophisticated and extendable strategies for Groebner base computation. BRiAl features a powerful reference implementation for Groebner basis computation.

This package contains the BRiAl Python 3 module.

Bumps is a set of routines for curve fitting and uncertainty analysis from a Bayesian perspective. In addition to traditional optimizers which search for the best minimum they can find in the search space, bumps provides uncertainty analysis which explores all viable minima and finds confidence intervals on the parameters based on uncertainty in the measured values. Bumps has been used for systems of up to 100 parameters with tight constraints on the parameters. Full uncertainty analysis requires hundreds of thousands of function evaluations, which is only feasible for cheap functions, systems with many processors, or lots of patience.

Bumps includes several traditional local optimizers such as Nelder-Mead simplex, BFGS and differential evolution. Bumps uncertainty analysis uses Markov chain Monte Carlo to explore the parameter space. Although it was created for curve fitting problems, Bumps can explore any probability density function, such as those defined by PyMC. In particular, the bumps uncertainty analysis works well with correlated parameters.

Bumps can be used as a library within your own applications, or as a framework for fitting, complete with a graphical user interface to manage your models.

Optlang is a Python package for solving mathematical optimization problems, i.e. maximizing or minimizing an objective function over a set of variables subject to a number of constraints. Optlang provides a common interface to a series of optimization tools, so different solver backends can be changed in a transparent way. Optlang's object-oriented API takes advantage of the symbolic math library sympy to allow objective functions and constraints to be easily formulated from symbolic expressions of variables.

This package installs the library for Python 3.

Vienna Computing Library (ViennaCL) è una libreria scientifica computazionale libera e open-source scritta in C++ e fornisce backend di calcolo CUDA, OpenCL e OpenMP. Permette un accesso semplice e ad alto livello alle vaste risorse di calcolo disponibili su architetture parallele come le GPU, ed è focalizzata principalmente sulle operazioni di algebra lineare comune (BLAS livelli 1, 2 e 3) e sulla risoluzione di grandi sistemi di equazioni per mezzo di metodi iterativi con precondizionatori facoltativi.

Questo pacchetto fornisce i collegamenti Python 3 per ViennaCL, PyViennaCL, che permettono di sfruttare la potenza computazionale di ViennaCL nel contesto dell'ecosistema scientifico di Python.

UFL (Unified Form Language) è un linguaggio unificato per la definizione di forme delle variazioni intese per la discretizzazione di elementi finiti. Più precisamente, definisce un'interfaccia fissa per scegliere spazi di elementi finiti e definire espressioni per forme deboli in una notazione vicina alla notazione matematica. I compilatori di forme FFC e SyFi usano UFL come loro interfaccia per l'utente finale, producendo implementazioni UFC come loro output.

Questo pacchetto installa la libreria per Python 3.

Givaro is a C++ library for arithmetic and algebraic computations. Its main features are implementations of the basic arithmetic of many mathematical entities: Primes fields, Extensions Fields, Finite Fields, Finite Rings, Polynomials, Algebraic numbers, and Arbitrary precision integers and rationals (C++ wrappers over gmp).

Givaro also provides data-structures and templated classes for the manipulation of basic algebraic objects, such as vectors, matrices (dense, sparse, structured), univariate polynomials (and therefore recursive multivariate).

It contains different program modules and is fully compatible with the LinBox linear algebra library and the Athapascan environment, which permits parallel programming.

This is a transitional dummy package, Debian no longer ships Developer Documentation for Givaro. This 'givaro-dev-doc' package can be safely removed from the system if no other package depends on it.

Un poliedro convesso è l'insieme di punti che soddisfano una famiglia finita di disuguaglianze lineari. Lo studio dei vertici e dei raggi estremi di tali sistemi è utile e importante ad esempio in studi matematici e di ottimizzazione. In un'interpretazione duale, trovare i vertici di un poliedro (limitato) è equivalente a trovare l'involucro convesso (disuguaglianze limite) di un insieme di punti (di dimensioni arbitrarie). Lrs (lexicographic reverse search) ha due importanti funzionalità che possono essere molto importanti per alcune applicazioni: funziona in aritmetica esatta e consuma memoria in modo proporzionale all'input, indipendentemente da quando grande sia l'output.

Questo pacchetto contiene header opzionali e un collegamento simbolico senza numero di versione alla libreria, utili agli sviluppatori.

MTJ is designed to be used as a library for developing numerical applications, both for small and large scale computations. The library is based on BLAS and LAPACK for its dense and structured sparse computations, and on the Templates project for unstructured sparse operations.

MTJ uses the netlib-java project as a backend, which can be set up to use machine-optimised BLAS libraries for improved performance of dense matrix operations, falling back to a pure Java implementation. This ensures perfect portability, while allowing for improved performance in a production environment.

Sollya è un ambiente di strumenti e una libreria per lo sviluppo sicuro di codice in virgola mobile. Permette di eseguire comodamente calcoli con aritmetica a intervalli con precisione multipla. È indirizzata particolarmente all'implementazione automatica di librerie matematiche in virgola mobile.

Inizialmente Sollya era pensato più specificamente per chi volesse implementare funzioni numeriche nelle librerie matematiche (ad esempio exp, arccos, tanh, ecc.), in seguito si è evoluto ed è ora diventato interessante non solo per gli sviluppatori di librerie matematiche, ma anche per tutti coloro che necessitano di eseguire esperimenti numerici in un ambiente sicuro riguardo agli errori di arrotondamento.

Questo pacchetto fornisce la libreria statica, i collegamenti simbolici e gli header necessari per lo sviluppo.

The Trilinos Project is an effort to develop and implement robust parallel algorithms using modern object-oriented software design, while still leveraging the value of established numerical libraries such as PETSc, Aztec, the BLAS and LAPACK. It emphasizes abstract interfaces for maximum flexibility of component interchanging, and provides a full-featured set of concrete classes that implement all abstract interfaces.

This package contains the headers and static libraries.

OpenTURNS è uno strumento potente e universale per trattare e quantificare incertezze in simulazioni numeriche per progettazione, ottimizzazione e controllo. Permette studi analitici sia di sensibilità sia di affidabilità:

  • definire l'output di interesse e i criteri di decisione;
  • quantificare e creare modelli per la fonte di incertezza;
  • propagare incertezze o analizzare la sensibilità e
  • classificare le fonti di incertezza.

OenTURNS è un vasto progetto con più di 300 classi C++, che usa software rinomato e ben supportato, come R per i metodi statistici e BLAS/LAPACK per l'algebra lineare.

Questo pacchetto fornisce esempi che sono scritti in C++ oppure in Python.

Sono principalmente usati come test di validazione per l'intera piattaforma, ma possono anche essere visti come tutorial per principianti.

TestU01 is a software library, implemented in the ANSI C language, and offering a collection of utilities for the empirical statistical testing of uniform random number generators.

TestU01 implements several types of random number generators in generic form, as well as many specific generators proposed in the literature or found in widely-used software. It provides general implementations of the classical statistical tests for random number generators, as well as several others proposed in the literature, and some original ones. These tests can be applied to the generators predefined in the library and to user-defined generators. Specific tests suites for either sequences of uniform random numbers in [0,1] or bit sequences are also provided, as well as basic tools for plotting vectors of points produced by generators and more advanced tools for more involved tests and usage.

This package contains the static libraries and symbolic links that developers using the TestU01 libraries will need.

levmar is a native ANSI C implementation of the Levenberg-Marquardt optimization algorithm. Both unconstrained and constrained (under linear equations, inequality and box constraints) Levenberg-Marquardt variants are included. The LM algorithm is an iterative technique that finds a local minimum of a function that is expressed as the sum of squares of nonlinear functions. It has become a standard technique for nonlinear least-squares problems and can be thought of as a combination of steepest descent and the Gauss-Newton method. When the current solution is far from the correct on, the algorithm behaves like a steepest descent method: slow, but guaranteed to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method.

This package contains the header file and the demo program.
