CommMatrixSparsityPattern() [1/2]

template<class M , class I >

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

inline

Constructor for the original side.

Parameters

m_	The matrix whose sparsity pattern is communicated.
idxset_	The index set corresponding to the local matrix.
aggidxset_	The index set corresponding to the redistributed matrix.

inline

Constructor for the redistruted side.

Parameters

m_	The matrix whose sparsity pattern is communicated.
idxset_	The index set corresponding to the local matrix.
aggidxset_	The index set corresponding to the redistributed matrix.
rowsize_	The row size for the redistributed owner rows.

Member Function Documentation

completeSparsityPattern()

template<class M , class I >

void Dune::CommMatrixSparsityPattern< M, I >::completeSparsityPattern ( std::vector< std::set< size_type > >  add_sparsity )

inline

Completes the sparsity pattern of the redistributed matrix with data from copy rows for the novlp case.

After the pattern communication this function can be used.

Parameters

add_sparsity

Sparsity pattern from the copy rows.

storeSparsityPattern()

template<class M , class I >

void Dune::CommMatrixSparsityPattern< M, I >::storeSparsityPattern ( M &  m )

inline

Creates and stores the sparsity pattern of the redistributed matrix.

After the pattern is communicated this function can be used.

Parameters

m	The matrix to build.
