Inheritance diagram for sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >:

Detailed Description

template<class InDataTypes, class OutDataTypes>
class sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >

Variant of EigenBaseSparseMatrix, capable of block-view access. The blocks correspond to matrix blocks of the size of the DataTypes Deriv.

There are two ways of filling the matrix:

Random block access is provided by method wBlock. Use compress() after the last insertion.
Block rows can be efficiently appended using methods beginBlockRow, createBlock, endBlockRow. Use compress() after the last insertion. The rows must be created in increasing index order.

The two ways of filling the matrix can not be used at the same time.

◆ beginBlockRow()

template<class InDataTypes , class OutDataTypes >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::beginBlockRow ( unsigned row )

inline

Prepare the insertion of a new row of blocks in the matrix. Then create blocks using createBlock( unsigned column, const Block& b ). Then finally use endBlockRow() or endSortedBlockRow() to validate the row insertion.

See also: createBlock( unsigned column, const Block& b ); endBlockRow()

Warning: empty rows should be created with a call to beginBlockRow + endSortedBlockRow

◆ copyFrom()

template<class InDataTypes , class OutDataTypes >

template<class AnyReal >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::copyFrom ( const CompressedRowSparseMatrix< type::Mat< Nout, Nin, AnyReal > > & crs )

inline

Set from a CompressedRowSparseMatrix.

Precondition: crs must be compressed

◆ createBlock()

template<class InDataTypes , class OutDataTypes >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::createBlock	(	unsigned	column,
		const Block &	b
	)

inline

Create a block in the current row, which must be previously initialized using beginBlockRow(unsigned row).

If the blocks are NOT created in column order, call endBlockRow(). If the blocks are given in column order, endSortedBlockRow() will be more efficient.

The blocks are not actually created in the matrix until method endBlockRow()/endSortedBlockRow() is called.

Warning: the block must NOT already exist

◆ endBlockRow()

template<class InDataTypes , class OutDataTypes >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::endBlockRow ( )

inline

Finalize the creation of the current block row.

See also: beginBlockRow(unsigned row); createBlock( unsigned column, const Block& b )

If the block have been given in column order, endSortedBlockRow() is more efficient.

◆ endSortedBlockRow()

template<class InDataTypes , class OutDataTypes >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::endSortedBlockRow ( )

inline

Finalize the creation of the current block row with blocks given in column order.

See also: beginBlockRow(unsigned row); createBlock( unsigned column, const Block& b ) in column order

◆ insertBackBlock()

template<class InDataTypes , class OutDataTypes >

void sofa::linearalgebra::EigenSparseMatrix< InDataTypes, OutDataTypes >::insertBackBlock	(	unsigned	row,
		unsigned	col,
		const Block &	b
	)

inline

Insert ASAP in the compressed matrix. There must be no value at this place already.

Warning: basically works only if there is only one block on the row; empty rows should be created with a call to beginBlockRow + endSortedBlockRow
