A vector of 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 354 of file matrix_block.h.
using MatrixBlockVector< MatrixType >::size_type = types::global_dof_index |
Declare type for container size.
Definition at line 360 of file matrix_block.h.
using MatrixBlockVector< MatrixType >::value_type = MatrixBlock<MatrixType> |
The type of object stored.
Definition at line 365 of file matrix_block.h.
using MatrixBlockVector< MatrixType >::ptr_type = std::shared_ptr<value_type> |
The pointer type used for storing the objects. We use a shard pointer, such that they get deleted automatically when not used anymore.
Definition at line 371 of file matrix_block.h.
|
inline |
Add a new matrix block at the position (row,column)
in the block system.
Definition at line 849 of file matrix_block.h.
|
inline |
For matrices using a SparsityPattern, this function reinitializes each matrix in the vector with the correct pattern from the block system.
Definition at line 860 of file matrix_block.h.
|
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.
Definition at line 871 of file matrix_block.h.
std::size_t MatrixBlockVector< MatrixType >::memory_consumption | ( | ) | const |
The memory used by this object.
|
inline |
Access a constant reference to the block at position i.
Definition at line 888 of file matrix_block.h.
|
inline |
Access a reference to the block at position i.
Definition at line 896 of file matrix_block.h.
|
inline |
Access the matrix at position i for read and write access.
