PyMat v1.0 -- A Python-to-MATLAB interface (freeware) NumPy is a set of numerical extensions for Python that introduces a multidimensional array type and a rich set of matrix operations and mathematical functions. Users who have MATLAB 5 installed, however, may wish to take advantage of some of MATLAB's additional functions, including the plotting interface. The PyMat module acts as an interface between NumPy arrays in Python and a MATLAB engine session, allowing arrays to be passed back and forth and arbitrary commands to be executed in the MATLAB workspace. PyMat is usable on both UNIX and Win32 platforms, although there are some slight differences between the two (mainly due to MATLAB's limitations). Andrew Sterian asterian@umich.edu
