template<class Scalar>

void Playa::LoadableMatrix< Scalar >::addToElementBatch	(	int	numRows,
		int	rowBlockSize,
		const int *	globalRowIndices,
		int	numColumnsPerRow,
		const int *	globalColumnIndices,
		const Scalar *	values,
		const int *	skipRow
	)		[virtual]

Add to a batch of elements

Reimplemented in Playa::EpetraMatrix.

Definition at line 98 of file PlayaLoadableMatrix.hpp.

template<class Scalar>

virtual void Playa::LoadableMatrix< Scalar >::addToRow	(	int	globalRowIndex,
		int	nElemsToInsert,
		const int *	globalColumnIndices,
		const Scalar *	elementValues
	)		[pure virtual]

Insert a set of elements in a row, adding to any previously existing values. The nonzero structure of the matrix must have been determined at construction time.

Parameters:

globalRowIndex	the global index of the row to which these elements belong.
nElemsToInsert	the number of elements being inserted in this step
globalColumnIndices	array of column indices. Must be nElemsToInsert in length.
elements	array of element values. Must be nElemsToInsert in length

Implemented in Playa::EpetraMatrix, and Playa::DenseSerialMatrix.

template<class Scalar>

virtual void Playa::LoadableMatrix< Scalar >::zero

(

)

[pure virtual]

Set all elements to zero, preserving the existing structure

Implemented in Playa::EpetraMatrix, and Playa::DenseSerialMatrix.
