Member Function Documentation

operator()()

void sgpp::pde::LaplaceEnhancedDownBBLinearBoundary::operator() ( sgpp::base::DataMatrix &  source, sgpp::base::DataMatrix &  result, grid_iterator &  index, size_t  dim  )

virtual

This operations performs the calculation of down in the direction of dimension dim on a grid with Dirichlet 0 boundary conditions.

Parameters

source	sgpp::base::DataMatrix that contains the gridpoint's coefficients (values from the vector of the laplace operation)
result	sgpp::base::DataMatrix that contains the result of the down operation
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction', here all downs are calculated
