Detailed Description

template<typename MatrixType>
class MGMatrixBlockVector< MatrixType >

A vector of MGLevelObject<MatrixBlock>, which is implemented using shared pointers, in order to allow for copying and rearranging. Each matrix block can be identified by name.

Member Typedef Documentation

◆ size_type

template<typename MatrixType >
using MGMatrixBlockVector< MatrixType >::size_type = types::global_dof_index

Declare type for container size.

Definition at line 450 of file matrix_block.h.

◆ value_type

template<typename MatrixType >
using MGMatrixBlockVector< MatrixType >::value_type = MGLevelObject<MatrixBlock<MatrixType> >

The type of object stored.

Definition at line 455 of file matrix_block.h.

Constructor & Destructor Documentation

◆ MGMatrixBlockVector()

template<typename MatrixType >
MGMatrixBlockVector< MatrixType >::MGMatrixBlockVector ( const bool  edge_matrices = false,
const bool  edge_flux_matrices = false 
)
inline

Constructor, determining which matrices should be stored.

If edge_matrices is true, then objects for edge matrices for discretizations with degrees of freedom on faces are allocated.

If edge_flux_matrices is true, then objects for DG fluxes on the refinement edge are allocated.

Definition at line 914 of file matrix_block.h.

Member Function Documentation

◆ size()

template<typename MatrixType >
unsigned int MGMatrixBlockVector< MatrixType >::size
inline

The number of blocks.

Definition at line 923 of file matrix_block.h.

◆ add()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::add ( size_type  row,
size_type  column,
const std::string &  name 
)
inline

Add a new matrix block at the position (row,column) in the block system. The third argument allows to give the matrix a name for later identification.

Definition at line 931 of file matrix_block.h.

◆ reinit_matrix()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_matrix ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the level matrices.

Definition at line 1035 of file matrix_block.h.

◆ reinit_edge()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_edge ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the matrices for degrees of freedom on the refinement edge.

Definition at line 1057 of file matrix_block.h.

◆ reinit_edge_flux()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::reinit_edge_flux ( const MGLevelObject< BlockSparsityPattern > &  sparsity)
inline

For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.

This function reinitializes the flux matrices over the refinement edge.

Definition at line 1083 of file matrix_block.h.

◆ clear()

template<typename MatrixType >
void MGMatrixBlockVector< MatrixType >::clear ( bool  really_clean = false)
inline

Clear the object.

Since often only clearing of the individual matrices is desired, but not removing the blocks themselves, there is an optional argument. If the argument is missing or false, all matrices will be empty, but the size of this object and the block positions will not change. If really_clean is true, then the object will contain no blocks at the end.
