Re: C for Polynomial Fit

Howdy :

Does anybody know where I can find code for a C function to fit an (N-1)th order polynomial to N (x,y) data points. Actually I need to fit a 5th order polynomial to 11 x,y points.

Thanks folks,
Gary

In answer to Herr Bröker's post, I posted here because I hoped to get intelligent and helpful suggestions - which I did - many thanks to those folks who posted. (Actually, I need the code for an embedded application, but it will run in the background so I'm not overly concerned about resources).

I at least know where to start...I suppose it was always a faint hope that somebody would say "follow this link to the source for int UnconditionalPerfectPolyFit(int n, int m, double *X, double *Y, double *K)", but hey, it was worth a try.
