Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for ... [More] performing other numerical experiments. It may also be used as a batch-oriented language. [Less]

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods ... [More] like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD). [Less]

LAPACK provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated ... [More] matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision. Note: Ohloh's statistics are not accurate. LAPACK has dozens of major contributors, but most do not use any form of source control. Contributions are merged by only a few people, and then only in bursts. [Less]

Lib2geom (2Geom in private life) is a library developed for inkscape to provide a robust computational geometry framework. It is not a rendering library, instead concentrating on high level algorithms such as computing arc length.

An implementation of linear algebra numerical structures and methods for the CLR. NPack is unique in that it uses generics for matrix element definitions, and a set of matrix operations via an ... [More] interface, allowing a CLR-based operations engine as well as the opportunity to use GPGPU-based operation engines. NPack was initially ported from Java Matrix Package (JAMA) by the US National Institute of Standards and Technology (which was a Java reinterpretation of LINPACK). [Less]

XMDS is a code generator that integrates equations. You write them down in human readable form in a XML file, and it goes away and writes and compiles a C++ program that integrates those equations as ... [More] fast as it can possibly be done in your architecture. [Less]

The Universal Java Matrix Package (UJMP) is an open source Java library that provides sparse and dense matrix classes, as well as a large number of calculations for linear algebra like matrix ... [More] multiplication or matrix inverse. Operations like mean, correlation, standard deviation, replacement of missing values or mutual information are also supported. Matrices can be imported from and exported to a large number of file formats, also linking to JDBC databases is supported. The Universal Java Matrix Package supports multidimensional matrices as well as generic matrices with a specified object type and can also handle very large matrices even when they do not fit into memory. [Less]

The Meta.Numerics library brings scientific computing to the .NET platform. It offers an object-oriented API for matrix algebra, advanced functions of real and complex numbers, and statistics.

pyBoostInterval uses Cython to wrap the Boost Interval library in Python. The idea is to have a class "Interval" in Python with all the necessary methods and functions. It should still be possible ... [More] to program near C speed due to Cython's ability to generate C code without the overhead of intermediate Python objects. Current Statuspre-alpha: development started, help is welcome! Get itsource code, download python setup.py build_ext --inplace(probably edit setup.py for your correct include_ext paths) WikiIntroduction [Less]

pyFilib uses Cython to wrap the Filib++ Interval library in Python. The idea is to have a class "Interval" in Python with all the necessary methods and functions. It should still be possible to ... [More] program near C speed due to Cython's ability to generate C code without the overhead of intermediate Python objects. Current Statusnull [Less]
