Scilab

(from the scilab homepage...) Scilab is a scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications. Scilab is an open source software. Since 1994 it has been distributed freely along with the source code ... [More] via the Internet. It is currently used in educational and industrial environments around the world. Scilab is now maintained by Scilab Enterprises: http://www.scilab-enterprises.com/ Note that Scilab has been using code review since 2010 (explaining the diminution in term of number of commits).

Eigen

claimed by KDE

Eigen is a C++ template library for linear algebra (vectors, matrices, and related algorithms). * It supports tiny, dense, and sparse matrices (the latter is still experimental), fully integrated with one another. * It takes full advantage of expression templates to provide a great API. For ... [More] example, m.row(i)+=m.row(j) just works. * Expression templates are also the basis for many optimizations: automatic determination of which temporaries to remove, and intelligent explicit vectorization (SSE and ALtiVec). * Performance is on par with the best BLAS implementations (see http://eigen.tuxfamily.org/index.php?title=Benchmark). * It keeps in mind the real needs of apps, for example the geometry features needed for 3D graphics [Less]

Math.NET Numerics

A mathematical open source library written in C#/.Net, aiming to provide a self contained clean framework for symbolic algebraic and numerical / scientific computations.

Armadillo C++ Library

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional ... [More] integration with LAPACK and ATLAS libraries. A delayed evaluation approach is employed (during compile time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language like Matlab or Octave. [Less]

NPack

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 interface, allowing a CLR-based operations engine as well as the opportunity to use GPGPU-based operation ... [More] 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]

Universal Java Matrix Package (UJMP)

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 multiplication or matrix inverse. Operations like mean, correlation, standard deviation, replacement of ... [More] 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.

Elemental (linear algebra)

Distributed-memory dense linear algebra.

Jama

Jama - Java Matrix OSGi version with tycho build and additional features

SimpleNumericalLibrary

A simple matrix and vector library. It contain basic matrix and vector operations, linear and non-linear system solvers, gauss integrator, and others

mathnetics

Mathnetics is an API for creating advanced, interactive, web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. Mathnetics also features rendering of 3D objects onto an SVG canvas (to do ... [More] so, it includes certain utilities such as browser sniffing, DOM node selection and DOM readiness detection) which is quite robust. A few basic 3D objects are given: Line, Sphere, Cube. But the user can define any 3D object desired as per the specification. Eventually, a GUI editor will be built with which anyone can create their own applications at a high-level instead of by coding line-by-line. View the current API documentation at: http://cis.jhu.edu/~shanest/js/mathnetics/docs/ Being at a not entirely stable release yet, the API is changing. I will post a definite and final API when it is ready. Some proofs of concept (a full-blown test suite will come shortly) can be seen at: http://cis.jhu.edu/~shanest/js/mathnetics/src/svg/surface.html (z=f(x,y) surface rendering) http://cis.jhu.edu/~shanest/js/mathnetics/src/svg/testdraw.html (3D rendering/animation) http://cis.jhu.edu/~shanest/js/mathnetics/src/svg/testbutton.html (3D buttons) http://cis.jhu.edu/~shanest/js/mathnetics/src/svg/t.html (2D function plotting/animation) [Less]
