Non linear equation solver - Newton-Raphson

[spranto]

Hi to you all,

This is my first post. I'm having troubles finding one suitable code line to solve a 3 non linear equation system. I'm here asking if someone allready done that and if it possible to share that with me, if not if someone can point me in the wright direction to achieve this goal.

Thank's in advance!

If you post the equations and how you would caclute it out by hand you would be more likely to get assistance.

The equations are simple. They are allways this type:

a*x+b*y+c*y=0

d*x+e*y+f*z=0

x^2+y^2+z^2-1=0

Thank's for the tip but I allready seen that. That's for solving only one equation.

By the way, let me tell you that the method doesen't have to be newton-raphson as long as it prove it self to be good.

Help me with this please!

Thank's again

Not sure I can solve any of those equations as listed by hand so I wouldn't be able to write code to do it.

Thank you for your answer but I've solved the problem using another algorithm not involving this equation system.
