Detailed Description

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

Utility class to communicate and build the sparsity pattern of a redistributed matrix.

Template Parameters
MThe type of the matrix that the sparsity pattern is communicated of.
IThe type of the index set.

Constructor & Destructor Documentation

◆ 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.

◆ CommMatrixSparsityPattern() [2/2]

template<class M , class I >
Dune::CommMatrixSparsityPattern< M, I >::CommMatrixSparsityPattern ( const M &  m_,
const Dune::GlobalLookupIndexSet< I > &  idxset_,
const I &  aggidxset_,
const std::vector< typename M::size_type > &  rowsize_ 
)
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_sparsitySparsity 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
mThe matrix to build.
