There is a matlab/octave interface to it. Look at the following reference on http://www.math.uic.edu/~jan/ I don't know more about this since I am also at the moment collecting information on how to solve a large system of polynomial equations. Yun Guan and Jan Verschelde: PHClab: A MATLAB/Octave

1. I would recommend looking at phcpack, it is designed to exploit the special nature of large polynomial systems, however, supposedly I believe it is sometimes difficult to compile, I've never used it but it might be better suited to your problem. http://www.math.uic.edu/~jan/download.html 2. T
