Rouhollah Basirat

Hi,

MATLAB is a fast method for solving.

Richard Epenoy

Hi, I agree with Rouhollah, you can use the fsolve function from MATLAB

Nianqiang Li

Yes, Matlab does help a lot, both for time-independent and time-dependent solutions.

Tamas Kalmar-Nagy

Do you mean algebraic equations?

Depending on the equations, there may even be analytic solutions.

One would need to see the equations to provide a more detailed answer.

Mathematica can help tremendously in finding analytical solutions.

Béla Vizvári

For numerical solution try Newton's method. If you need algebraic solution, maybe Maple may help a lot.

Behrooz Ghasemishabankareh

Hi. The easiest way is to use fmincon() function in Matlab. Note that, It may not give you the global optima.
