Re:[Help-gsl] What is XSTRIDE in the least square fit functions?

stride stride to 2. So if you want to fit each member of both input/output arrays, set both xstride and ystride to 1, as it is in least squares example http://www.gnu.org/software/gsl/manual/html_node/Fitting-Examples.html I hope this helps you best regards Petr Ent Původní

Re: [Help-gsl] fitting - nonconstant point distance

, but it only cares how to minimize it. Basicly, it has only vector of numbers which it should make as small as possilbe. Am I right? So I can give him residuals in points for example 0, 100, 101 and 1048 and it should be ok Best Regards Petr Ent On 25/11/06, Petr Ent [EMAIL PROTECTED] wrote: I

to influence the iteration progress? Some borders for solver which cannot be passed? Or is it possible to choose some non-derivative solver (I have not found any type of gsl_multifit_fsolver) and will it be better? I will appreciate any idea best regards Petr Ent
