With considerable help from the GSL community, I have put together a testing framework for fitting data using the GSL. It was designed a) for multiple fitting functions, and b) for functions with unknown analytical derivatives. It also fits using nonlinear least squares, or multidimensional minimization, or simmulated annealing. It might be overkill for you Eric, but it's not that many lines of code, so it still may be helpfull. http://neutron.nrc-cnrc.gc.ca/people/harroun/documents/test-gsl.tar.gz Thad -------------------------------------- [EMAIL PROTECTED] Canadian Neutron Beam Centre National Research Council Canada Building 459, Station 18 Chalk River Laboratories Chalk River, Ontario CANADA K0J 1J0 Pho:613-584-8811 x6237 Fax:613-584-4040 http://neutron.nrc-cnrc.gc.ca/people/harroun CONFIDENTIAL AND PRIVILEGED INFORMATION NOTICE This e-mail, and any attachments, may contain information that is confidential, subject to copyright, or exempt from disclosure.
