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 345 of file matrix_block.h.
| using MatrixBlockVector< MatrixType >::size_type = types::global_dof_index |
Declare type for container size.
Definition at line 351 of file matrix_block.h.
| using MatrixBlockVector< MatrixType >::value_type = MatrixBlock<MatrixType> |
The type of object stored.
Definition at line 356 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 362 of file matrix_block.h.
|
inline |
Add a new matrix block at the position (row,column) in the block system.
Definition at line 851 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 862 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 873 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 890 of file matrix_block.h.
|
inline |
Access a reference to the block at position i.
Definition at line 898 of file matrix_block.h.
|
inline |
Access the matrix at position i for read and write access.
