Description

Dark Energy equation of state: $w(\alpha)$ approximated by a cubic spline.

Functions

nc_hicosmo_de_wspline_new ()

NcHICosmoDEWSpline *
nc_hicosmo_de_wspline_new (gsize nknots,
                           const gdouble z_f);

This function instantiates a new object of type NcHICosmoDEWSpline.

Parameters

nknots

number of knots in the $w(z)$ spline

  

z_f

redshift $z_f$ of the last knot.

  

Returns

A new NcHICosmoDEWSpline

NcmVector *
nc_hicosmo_de_wspline_get_alpha (NcHICosmoDEWSpline *wspline);

Gets vector with the current knots in $\alpha$.

Parameters

wspline

a NcHICosmoDEWSpline

  

Returns

A new NcmVector.
