[Help-gsl] getting cubicsline interpolation coefficients

[Serle Shuman]

Hi,

 

I'm needing to obtain the cubic spline interpolation co-efficients at each
abscissa. Is there a way to do this with gsl. Could someone send an example.
Ideally I would like an array containing an array of coefficients at each
point. I then need to plug these into a matrix solver as part of a
collocation solver.

 

Thanks in advance,

Serle
