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

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 ... [More] 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]

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

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 classes, and a large library of related functions. ... [More] 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]

Flex/Actionscript Math Library (as3mathlib)The Flex/Actionscript Math Library (as3mathlib) is intended to provide a rudimentary numerical analysis toolkit for the Actionscript/Flex programming environment. It is based off of the WIS Actionscript 2 ... [More] libraries, which are still available DetailsThis library includes support for Geometric Objects and Intersection calculations Integral and Differential equation calculations Bezier, Quadric, Polynomial, Complex, Vector and Matrix calculations Symbolic expression parsing StatusThis library has just been converted from Actionscript 2 to Actionscript 3. It is not ready for general use. It compiles with no errors and only a few warnings. It has not been sanity-checked for compatibility or correctness It has not been subjected to unit testing It still uses deprecated AS2 practices and vernacular Its design is heavily functional-programming oriented, and doesn't (for the most part) present an object-oriented, pattern-design interface. On the positive side, The scope and architecture are in place All of the algorithms are in place and were well-tested in their former incarnation The code base is nicely modular, so different developers can break off little pieces and get them working independently. GoalsOur two, no three primary goals -- our five primary goals are: Correctness: the library is accompanied by a complete set of regression tests. Clarity of code: the routines are well commented and follow best practices of software engineering. Modularity: In most cases users will need only a few routines out of the package. To the extent possible, this should require bringing in a correspondingly small portion of the library. Flexibility: A few, general, easily understood routines are more desirable than a comprehensive deathmarch through advanced numerical methods. Think "Numerical Recipes", not "Lapack". Performance: Actionscript will never be a premiere high-performance computing environment. With that said, the library should support prototyping applications calculations of modest scope. Routines that don't meet this modest standard won't be included. [Less]
