Description

This object subclasses NcmMSetTransKern and implements a catalog sampler.

Implementation of a catalog sampler class, capable of drawing samples from a catalog of points. Users can select the desired sampling method as described in NcmMSetTransKernCatSampling.

**Key Functionality:**

This class is designed for scenarios where sampling from a pre-existing catalog is useful, providing flexibility through the selection of various sampling methods described in NcmMSetTransKernCatSampling.

Functions

ncm_mset_trans_kern_cat_new ()

NcmMSetTransKernCat *
ncm_mset_trans_kern_cat_new (NcmMSetCatalog *mcat,
                             NcmStatsDist *sd);

New NcmMSetTransKernCat from mcat catalog with the interpolation object sd .

Parameters

mcat

a NcmMSetCatalog

  

sd

a NcmStatsDist.

[allow-none]

Returns

a new NcmMSetTransKernCat.

                                      NcmMSetTransKernCatSampling sampling);

Sets the sampling type to sampling .

Parameters

tcat

ncm_mset_trans_kern_cat_get_sampling ()

NcmMSetTransKernCatSampling
ncm_mset_trans_kern_cat_get_sampling (NcmMSetTransKernCat *tcat);

Gets the sampling type.

Parameters

tcat

Returns

the current sampling type NcmMSetTransKernCat.

ncm_mset_trans_kern_cat_reset ()

void
ncm_mset_trans_kern_cat_reset (NcmMSetTransKernCat *tcat);
