System of non linear equotions solver
i'am looking for a lib that solves a system of non linear equations.

Somewhat like this : http://softmath.com/math-solver/solve-system-of-equations.html#v1=x%2Cy%2Cz&v2=3&v3=x%5E2%2By%5E2%2Bz%5E2%3D200&v4=x%5E2%2B(y%2B200)%5E2%2Bz%5E2%3D300&v5=x%5E2%2By%5E2%2B(z%2B300)%5E2%3D400

I have been searching for 2 hours now and nothing..

Thnx in advance.
Kind Regards.
