Member Function Documentation

◆ operator()()

void sgpp::pde::PhiPhiUpBBLinearBoundary::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

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	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 from sgpp::pde::PhiPhiUpBBLinear.
