Hello,
have currently used your FitToFunction algorithm to fitting FabryPerot ringes from CCDChip. It works great!!! Thanks a lot for the library.
I have just one question: what for a algorithm behind it? (LevenbergMarquardt)?
Thanks!



FitToFunction uses Powell's algorithm, a line search algorithm for optimizing arbitrary functions without derivatives. LevenbergMarquardt is a great algorithm, but it requires derivatives, so to use it we would either have to ask uses to supply derivative
functions or compute them numerically.
