[Bug-gsl] gsl splines

[Michael Grabchak]

Hello,

I was working with the spline functions from gsl.  One thing that I have
noticed is that when the size is large (>400) gsl_spline_eval starts
returning NANs.  I could not find anything about this in the reference
manual.  Of course I can just break up the vector into several, however, I
was wondering if there is a better way.  Also, I do not know if it matters
but I was using the cubic spline interpolation.

thank you very much,
Michael
