Detailed Description

template<typename MatrixType>
class MatrixBlockVector< MatrixType >

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.

Author: Baerbel Janssen, Guido Kanschat, 2010

Member Typedef Documentation

◆ size_type

template<typename MatrixType>

typedef types::global_dof_index MatrixBlockVector< MatrixType >::size_type

Declare type for container size.

Definition at line 337 of file matrix_block.h.

◆ value_type

template<typename MatrixType>

typedef MatrixBlock<MatrixType> MatrixBlockVector< MatrixType >::value_type

The type of object stored.

Definition at line 342 of file matrix_block.h.

◆ ptr_type

template<typename MatrixType>

typedef std::shared_ptr<value_type> MatrixBlockVector< MatrixType >::ptr_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 348 of file matrix_block.h.

Member Function Documentation

◆ add()

template<typename MatrixType >

void MatrixBlockVector< 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.

Definition at line 823 of file matrix_block.h.

◆ reinit()

template<typename MatrixType >

void MatrixBlockVector< MatrixType >::reinit ( const BlockSparsityPattern & sparsity )

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 834 of file matrix_block.h.

◆ clear()

template<typename MatrixType >

void MatrixBlockVector< 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.

Definition at line 845 of file matrix_block.h.

◆ memory_consumption()

template<typename MatrixType>

std::size_t MatrixBlockVector< MatrixType >::memory_consumption ( ) const

The memory used by this object.

◆ block() [1/2]

template<typename MatrixType >

const MatrixBlock< MatrixType > & MatrixBlockVector< MatrixType >::block ( size_type i ) const

inline

Access a constant reference to the block at position i.

Definition at line 862 of file matrix_block.h.

◆ block() [2/2]

template<typename MatrixType >

MatrixBlock< MatrixType > & MatrixBlockVector< MatrixType >::block ( size_type i )

inline

Access a reference to the block at position i.

Definition at line 870 of file matrix_block.h.

◆ matrix()

template<typename MatrixType >

MatrixType & MatrixBlockVector< MatrixType >::matrix ( size_type i )

inline

Access the matrix at position i for read and write access.

Definition at line 878 of file matrix_block.h.
