Hi, I am a newcomer to Java, and I am dealing with a problem. I need to solve a system of 3 equations (3 unknown variables) which are not linear. I have been using mathematica, where finding roots is quit straightforward , all you had to do is define
f(x,y,z), g(x,y,z), h(x,y,z) and call FindRoot (it uses Newton Raphson methodology to find roots).

I was searching for a libreary that may help doing that, instead of implementing NR on my own (which I can't, because I lack the knowledge of programming and numeric analysis).

I came accross Apache Commons Math, where there seems to be a NR solver, but there are no examples of how using it in system of equations.



Can someone help me? Thank you in advance
