Function Documentation

pastixExpand()

void pastixExpand	(	const pastix_data_t *	pastix_data,
		spmatrix_t *	spm
	)

Expand an spm structure and the already computed data structure associated if any.

Parameters

[in]	pastix_data	The pastix context in which the spm is used
[in]	spm	The multi-dof sparse matrix to expand into a single dof sparse matrix. On exit, spm contains the expanded matrix. The compressed form of the matrix is destroyed.
