MATLAB(untested, download at your own risk)

Short for Matrix Laboratory, Matlab is a technical computing environment for high-performance numeric computation and visualization. It integrates numerical analysis, matrix computation, signal processing, and graphics in an easy-to-use environment where problems and solutions are expressed just as they are written mathematically, without traditional programming. Typical uses include general-purpose numeric computation, algorithm prototyping, and special-purpose problem solving with matrix formulations that arise in disciplines such as linear algebra, structural analysis, statistics, and digital signal processing.
