Software for analysis of dynamical systems?

[Michel Loreau]

I am looking for a PC-software allowing analysis and simulation of
nonlinear dynamical systems, for applications in theoretical ecology.
I know there are several of them on the market, but I have not had a
chance to try any. Could anybody give me advice and information on this
matter?

Please reply by e-mail to mloreau at resulb.ulb.ac.be. Thanks in advance.
