Description

This object implements the necessary functions to compute a cubic spline with where the user provides the second derivatives of the function.

Functions

ncm_spline_cubic_d2_new ()

NcmSplineCubicD2 *
ncm_spline_cubic_d2_new (NcmVector *xv,
                         NcmVector *yv,
                         NcmVector *d2yv,
                         gboolean init);

This function returns a new NcmSpline setting all its members. It makes a copy of the d2yv vector and saves it internally.

Parameters

xv	NcmVector of knots
yv	NcmVector of the values of the function to be interpolated, computed at `xv`
d2yv	NcmVector of the values of the second derivative of the function to be interpolated, computed at `xv`
init	TRUE to prepare the new NcmSpline or FALSE to not prepare it

Returns

a new NcmSpline.
