Michael,

In reply to your near for a linear, least square fit, I thought I would send you a copy of DataAnalyzer, an application that our students use for curve fitting.

DataAnalyzer.app

Your comments on the application would be appreciated.

Subject: Linear least squares

I'm looking for a C routine that will do linear least squares fit (and actually, I might need non-linear sometime soon).  Does anyone know of a general set of 'C' routines for such numerics that is publicly available?

I've already spent some time with the Fortran version of "Numerical Recipes" (conversion by hand to C), but the code is not well structured and not explained very clearly (for the SVD technique), so I can't get it to work.  Also, they have a very restricted re-distribution policy for their code, and I hope to make my completed project publicly available once done, so that would cause problems.

Any references would be appreciated.

Thanks
