Hello, I have worked with this functions for a while and I think this parameters are "steps" in input/output arrays. With stride, you say for how many members you should move before reading next value.
For example, if you want to fit only 1., 3., 5., ... member of input array, you simply set its 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 zpráva ------------ > Od: Chris Albertson <[EMAIL PROTECTED]> > Předmět: [Help-gsl] What is "XSTRIDE" in the least square fit functions? > Datum: 12.4.2007 05:24:33 > ---------------------------------------- > I'm getting unexpected results.
