Hello!
Does anybody know if it’s possible to do Nonlinear Least Squares Fitting with ROOT? Maybe one of the new MathCore or MathMore has some class for doing it?
I have a complicated function that even Mathematica 5.2 can’t solve the residues derivate linear equation, so no chance of using Linear Least Squares Fitting… and we need something fast, so we can’t use Minuit routines either
I can always implement it myself, but if it already exists, there is no point int re-inventing the wheel!

Thankx,
