the length of each of the three arrays.

Returns
the total number of operations

Implements sgpp::base::OperationStencilHierarchisation.

References surplusStencil.

const IndexStencil& sgpp::base::OperationStencilHierarchisationLinear::getSurplusStencil ( ) const
inlineoverridevirtual

This is an index array whose contents refer to the indices associated with the grid points by means of the storage scheme used.

Returns
the surpluses array

Implements sgpp::base::OperationStencilHierarchisation.

const WeightStencil& sgpp::base::OperationStencilHierarchisationLinear::getWeightStencil ( ) const
inlineoverridevirtual

Access to the results of the hierarchisation operation.

Returns
the weights array

Implements sgpp::base::OperationStencilHierarchisation.
