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 ... [More] with one another. * It takes full advantage of expression templates to provide a great API. For 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]

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

(from the scilab homepage...) Scilab is a scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications. ... [More] Scilab is an open source software. Since 1994 it has been distributed freely along with the source code via the Internet. It is currently used in educational and industrial environments around the world. Scilab is now the responsibility of the Scilab Consortium, launched in May 2003. There are currently 25 members in Scilab Consortium. [Less]

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]

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.

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

The Configurable Math Library (CML) is an open-source C++ library designed for use in games, graphics, computational geometry, and related applications. It includes vector, matrix, and quaternion ... [More] classes, and a large library of related functions. Vectors and matrices can be of arbitrary size, and all classes are parameterized by element type. Other options, such as matrix layout and choice of row- or column-vector notation, are available as well. The CML can be used as an extension to an existing math library, in lieu of or as an extension to the DirectX math library, or as a drop-in solution for OpenGL-based applications. [Less]

VMMLib is a vector and matrix math library implemented using C++ templates, thus making it very easy to integrate into other libraries and programs.

CocoaMathThis is a kit of useful math related classes for matrices, vector, quaternions and even complex quaternions known as biquaternions.

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 ... [More] calculations can be done. Mathnetics also features rendering of 3D objects onto an SVG canvas (to do 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]
