Hi all,

I hope you can guide me on this matter

I have a surface (i.e. s=f(x,y)) that I need to fit with a polynomial function using levenberg-marquardt algorithm.

In matlab it's quite easy, since I use lsqnonlin function, but I'm getting desperated to do this in C#

Any idea?

I read that alglib has this algorithm but I just see the example to fit a curve (i.e. s=f(x))

Thanks for your help!!
