Detailed Description

Class that implements the dehierarchisation on a linear sparse grid with boundaries.

Therefore the ()operator has to be implement in order to use the sweep algorithm for the grid traversal

Constructor & Destructor Documentation

◆ DehierarchisationLinearStretchedBoundary()

explicit

Constructor, must be bind to a grid.

Parameters

storage the grid storage object of the the grid, on which the dehierarchisation should be executed

Member Function Documentation

◆ operator()()

void sgpp::base::DehierarchisationLinearStretchedBoundary::operator()	(	DataVector &	source,
		DataVector &	result,
		grid_iterator &	index,
		size_t	dim
	)

overridevirtual

Implements operator() needed by the sweep class during the grid traversal.

This function is applied to the whole grid.

For level zero it's assumed, that both ansatz-functions do exist: 0,0 and 0,1 If one is missing this code might produce some bad errors (segmentation fault, wrong calculation result) So please assure that both functions do exist!

Parameters

source	this DataVector holds the linear base coefficients of the sparse grid's ansatz-functions
result	this DataVector holds the node base coefficients of the function that should be applied to the sparse grid
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction'
