Re: Non-linear Curve Fitting

David -

There is a package by a norwegian colleague, called Janhunen, that I
have used quite successfully for some nonlinear fits to functions 
such as

A Exp[ B x + C]

where A,B,C are the fit parameters. The method is used called something
like "Lev..-Marquardt" and can be found e.g. in Numerical Recipes.
The packages is on yoda under the directory JANHUNEN.

Hope this helps, Rudo
