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.
Definition at line 435 of file matrix_block.h.
| using MGMatrixBlockVector< MatrixType >::size_type = types::global_dof_index |
Declare type for container size.
Definition at line 441 of file matrix_block.h.
| using MGMatrixBlockVector< MatrixType >::value_type = MGLevelObject<MatrixBlock<MatrixType>> |
The type of object stored.

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 916 of file matrix_block.h.
|
inline |
The number of blocks.
Definition at line 925 of file matrix_block.h.
|
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.

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.

This function reinitializes the flux matrices over the refinement edge.

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.
