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

[Petr Ent]

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

I hope this helps you
best regards
