A symbolic toolbox that provides MATLAB users with all of the symbolic and high-precision numeric capabilities of Mathematica. It uses the MathLink communication standard supplied with Mathematica and the MEX facility of MATLAB. In addition, since MathLink can pass native MATLAB matrices (and not just strings) between Mathematica and MATLAB, it is quick and easy to construct matrices in either system and pass them to the other. One can freely mix Mathematica code and MATLAB code without the bother of writing M-files to convert matrices into strings and back. The Mathematica Symbolic Toolbox for MATLAB is implemented as a single MEX-file and the source code is included. Precompiled linux and windows executables are included. Installation instructions for MACs are included in the README.Version 2.0 has been updated from:http://library.wolfram.com/infocenter/MathSource/624 to work with MATLAB R2007b and Mathematica 6.0.
