Thanks for replying, no I haven't. But I will. I've just downloaded Maxima, and ASCEND and I'm taking a closer look at them. Which of these two programs do you think is best for solving system on non-linear equations? BTW, I don't expecting an analytic solution. My equations don't look too friendly ... (nasty logs! :-) )If you just want a numerical solution then try ASCEND or GAMS (or AMPL or...). The advantage here is that you can enter the equations in a fairly intuitive way and not have to worry about 'wiring it up' to the solver. The Excel Solver (or even maybe the new Open Office 3.0b Solver?) would be a good bet too. Maxima is really for getting analytic solutions, although it might be possible to get numerical solutions as well -- I'm not sure.What do you think of scilab's fsolve? -- I'm assuming you're an expert-type person in this area ;-) . I'm not liking ASCEND's documentation.

Both Scilab and Octave have good solvers. The advantage of Octave over Scilab is it's easier to get Matlab scripts running provided they don't use graphics. Also, check out Euler which has a Matlab like GUI interface for doing numerical analysis. Under Windows, it also interfaces to Maxima. http://mathsrv.ku-eichstaett.de/MGF/homes/grothmann/euler/
