Detailed Description

Class that implements the hierarchisation on a linear sparse grid.

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

sgpp::base::HierarchisationLinearStretched::HierarchisationLinearStretched ( 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::HierarchisationLinearStretched::~HierarchisationLinearStretched ( )
virtual

Destructor.

Member Function Documentation

void sgpp::base::HierarchisationLinearStretched::operator() ( DataVector source,
DataVector result,
grid_iterator index,
size_t  dim 
)
virtual

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

This function is applied to the whole grid.

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'

Reimplemented in sgpp::base::HierarchisationLinearStretchedBoundary.

Recursive hierarchisation algorithm, this algorithms works in-place -> source should be equal to result.

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'
flleft value of the current region regarded in this step of the recursion
frright value of the current region regarded in this step of the recursion
