Member Function Documentation

void PetscMatrix::add	(	int	m,
		int	n,
		scalar **	mat,
		int *	rows,
		int *	cols
	)			[virtual]

update the stiffness matrix

Parameters:

[in]	m	- number of rows of given block
[in]	n	- number of columns of given block
[in]	matrix	- block of values
[in]	rows	- array with row indexes
[in]	cols	- array with column indexes

Implements Matrix.
