NumCosmoMathSplinecurvature_density

Declaration [src]

gdouble
ncm_spline_curvature_density (
  NcmSpline* s,
  NcmSplineCurvatureType ctype,
  const gdouble x
)

Description [src]

Evaluates the curvature density $c(x)$ of the interpolated function at x, as selected by ctype (see NcmSplineCurvatureType). The spline must be prepared.

Parameters

ctype

Type: NcmSplineCurvatureType

A NcmSplineCurvatureType.

x

Type: const gdouble

A value of the abscissa axis.

Return value

Type: gdouble

The curvature density $c(x)$.
