Detailed Description

template<class M, class I>
struct Dune::CommMatrixRow< M, I >

Utility class for comunicating the matrix entries.

Template Parameters

M	The type of the matrix.
I	The type of the ParallelIndexSet.

Constructor & Destructor Documentation

CommMatrixRow() [1/2]

template<class M, class I>

Dune::CommMatrixRow< M, I >::CommMatrixRow ( M & m_, const Dune::GlobalLookupIndexSet< I > & idxset_, const I & aggidxset_ )

inline

Constructor.

Parameters

m_	The matrix to communicate the values. That is the local original matrix as the source of the communication and the redistributed at the target of the communication.
idxset_	The index set for the original matrix.
aggidxset_	The index set for the redistributed matrix.

CommMatrixRow() [2/2]

template<class M, class I>

Dune::CommMatrixRow< M, I >::CommMatrixRow ( M & m_, const Dune::GlobalLookupIndexSet< I > & idxset_, const I & aggidxset_, std::vector< size_t > & rowsize_ )

inline

Constructor.

Member Function Documentation

setOverlapRowsToDirichlet()

template<class M, class I>

void Dune::CommMatrixRow< M, I >::setOverlapRowsToDirichlet ( )

inline

Sets the non-owner rows correctly as Dirichlet boundaries.

This should be called after the communication.
