Cubic spline interpolation.


Hi,
I need the coeficient of a cubic spline interpolation. How can I get them out of the GSL structure after the usuals:


        gsl_interp_accel *acc
           = gsl_interp_accel_alloc ();
         gsl_spline *spline
           = gsl_spline_alloc (gsl_interp_cspline, 10);

gsl_spline_init (spline, x, y, 10);
calls?? I've poked around the GSL code and I know they are within the "spline" structure but I can't realize where.


Thanks in advance,
	Andrea.
