Details:
Hello, I have a problem with my code.
Indeed, it is working very well with gs 1.16 but since I've tried with the new
release, I have no warnings, no errors at compilation but the application
crashes.
My code (you can read all the code at:
https://free-astro.vinvin.tf/svn/siril/trunk/src/gradient.c (sorry for the bad
certificat) is something like that:
J = gsl_matrix_alloc (n, VarParam);
y = gsl_vector_alloc (n);
w = gsl_vector_alloc (n);
c = gsl_vector_alloc (VarParam);
cov = gsl_matrix_alloc (VarParam, VarParam);
[...]
gsl_multifit_linear_workspace * work = gsl_multifit_linear_alloc (n,
VarParam);
gsl_multifit_wlinear (J, w, y, c, cov, &chisq, work);
gsl_multifit_linear_free (work);
[...]
When I run the code I have:
gsl: multiwlinear.c:71: ERROR: size of workspace does not match size of
observation matrix
Default GSL error handler invoked.
So, gdb shows that the bug is on the line 204, i.e,
gsl_multifit_wlinear (J, w, y, c, cov, &chisq, work);
I have no clue to explain where the problem come from. Could help me please ?
Best regards,
