This operations performs the calculation of down in the direction of dimension dim on a grid with Dirichlet 0 boundary conditions.
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' |
Reimplemented in sgpp::pde::PhiPhiDownBBLinearStretchedBoundary.
