Detailed Description

Class that implements the hierarchisation 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

sgpp::base::HierarchisationLinearBoundary::HierarchisationLinearBoundary ( GridStorage storage)
explicit

Constructor, must be bind to a grid.

Parameters
storagethe grid storage object of the the grid, on which the hierarchisation should be executed
sgpp::base::HierarchisationLinearBoundary::~HierarchisationLinearBoundary ( )
override

Destructor.

Member Function Documentation

void sgpp::base::HierarchisationLinearBoundary::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
sourcethis DataVector holds the node base coefficients of the function that should be applied to the sparse grid
resultthis DataVector holds the linear base coefficients of the sparse grid's ansatz-functions
indexa iterator object of the grid
dimcurrent fixed dimension of the 'execution direction'
