operator()()

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

This operations performs the calculation of upGradient in the direction of dimension dim

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 down operation
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction'

rec()

void sgpp::pde::dPhidPhiUpModLinear::rec ( sgpp::base::DataVector &  source, sgpp::base::DataVector &  result, grid_iterator &  index, size_t  dim, double &  f  )

protected

recursive function for the calculation of upGradient

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
f	function value in the middle
