I want to analyze a system of ~200 ODE (non-linear) and want to calculate the stable points. Can you suggest a good software for the analysis. I am comfortable with MATLAB and C++.

I researched and found good things about MATCONT and XPPAUT. Are they the state-of-art in the field?

Thanks Ayesha

I personally use XPPAUT. It's a bit old-fashioned with a poor GUI but effective though. –  chemeng May 4 '12 at 17:45
    
@Ayesha: Are your ODEs polynomial? If so, finding the equilibria boils down to solving a polynomial system of equations, and Buchberger's algorithm may be useful. –  Rod Carvalho Sep 12 '12 at 20:48
