Hi Wang,
I understand now. Thanks very much!

Hi,
these parameters are used to control the step lengths of data
samplings. Consider data sequence x for example. The data you would
like to feed into this function may not be one by one but every two.
Then you need to let xstride be 2 to achieve that.
Best,

Hi,
I want to use gsl_fit_linear function. But I am puzzled withe the
parameters xstride and ystride.
Could anybody like to give some explanations ?
Thanks in advance.
Richard
PS. function signature :
int *gsl_fit_linear* (const double * x, const size_t xstride, const double
* y, const size_t ystride, size_t n, double * c0, double * c1, double *
cov00, double * cov01, double * cov11, double * sumsq)
