Detailed Description

template<class BSplines, ddc::BoundCond BcLower, ddc::BoundCond BcUpper>
class ddc::GrevilleInterpolationPoints< BSplines, BcLower, BcUpper >

A class which provides helper functions to initialise the Greville points from a B-Spline definition.

Template Parameters

BSplines	The bspline class relative to which the Greville points will be calculated.
BcLower	The lower boundary condition that will be used to build the splines.
BcUpper	The upper boundary condition that will be used to build the splines.

◆ get_sampling() [1/2]

static auto ddc::GrevilleInterpolationPoints< BSplines, BcLower, BcUpper >::get_sampling ( )

inlinestatic

Get the UniformPointSampling defining the Greville points.

This function is called when the result is a UniformPointSampling. This is the case when uniform splines are used with an odd degree and with boundary conditions which do not introduce additional interpolation points.

Template Parameters

Sampling The discrete dimension supporting the Greville points.
