Method

NumCosmoMathSplineset_func_grid1

Declaration [src]

void
ncm_spline_set_func_grid1 (
  NcmSpline* s,
  NcmSplineFuncType ftype,
  NcmSplineFuncF F,
  GObject* obj,
  gdouble xi,
  gdouble xf,
  gsize nnodes
)

Description [src]

This function fills the spline s with the function F values in a uniform grid within the range [xi, xf] and a total of nnodes knots.

The difference between #ncm_spline_set_func_grid is how the user function is passed. Here, it uses a NcmSplineFuncF function and it parameters are allocated in the object obj. This function is more suitable to be used within Python.

Parameters

ftype

Type: NcmSplineFuncType

A NcmSplineFuncType: must be either #NCM_SPLINE_FUNC_GRID_LINEAR or #NCM_SPLINE_FUNC_GRID_LOG.

F

Type: NcmSplineFuncF

Function to be interpolated.

obj

Type: GObject

GObject used by the function F.

The argument can be NULL.

The data is owned by the caller of the method.

xi

Type: gdouble

Lower knot.

xf

Type: gdouble

Upper knot.

nnodes

Type: gsize

Number of knots including both limits knots [xi, xf].
