Hi!
For the creation of interpolation objects, a certain number of data
points (varies depending on the interpolation type) is needed. The
function "gsl_interp_min_size" can be used to find this number.
However, "gsl_interp_min_size" takes an interpolation object as
argument, which can't be created with too few points. Thus, you can't
use the function to check whether you have enough points to create the
object, which kind of defeats its purpose.
I propose that "gsl_interp_min_size" be changed to the following:
unsigned int gsl_interp_min_size(const gsl_interp_type* T)
{
return T->min_size;
}
It would be called with an interpolation type ("gsl_interp_linear" etc.,
same as "gsl_interp_alloc"), not an object, to get minimum size required
for this type.
Best regards
Hendrik
