operator()()

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

virtual

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

Parameters

source	sgpp::base::DataVector that contains the gridpoint's coefficients (values from the vector of the laplace operation)
result	sgpp::base::DataVector that contains the result of the up operation
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction'

Reimplemented in sgpp::pde::PhiPhiUpBBLinearStretchedBoundary.

protected

recursive function for the calculation of Up without bounding Box support

Parameters

source	sgpp::base::DataVector that contains the coefficients of the ansatzfunction
result	sgpp::base::DataVector in which the result of the operation is stored
index	reference to a griditerator object that is used navigate through the grid
dim	the dimension in which the operation is executed
fl	function value on the left boundary, reference parameter
fr	function value on the right boundary, reference parameter
