NumCosmoHICosmoQSplinelp_norm

Declaration [src]

gdouble
nc_hicosmo_qspline_lp_norm (
  NcHICosmoQSpline* qspline,
  NcmSplineCurvatureType ctype,
  const gdouble p
)

Description [src]

Computes the domain-normalized $L_p$ norm of the $q(z)$ curvature density (selected by ctype) over the reconstruction range $[0, z_f]$. The case p = 2 yields the root-mean-square curvature; large p approaches the maximum (see ncm_spline_curvature_lp_norm()).

Parameters

ctype

Type: NcmSplineCurvatureType

A NcmSplineCurvatureType.

p

Type: const gdouble

The norm order $p > 0$.

Return value

Type: gdouble

The curvature $L_p$ norm.
