cpublok_zalloc_lrws()

void cpublok_zalloc_lrws	(	const SolverCblk *	cblk,
		const SolverBlok *	blok,
		pastix_lrblock_t *	lrblok,
		pastix_complex64_t *	ws
	)

Initialize a lrblock structure from a workspace from a specific block to the end of all blocks.

The lrblock structure must be allocated before.

Parameters

[in,out]	cblk	The column block associated to the initialization.
[in]	blok	The block representation associated to the initialization.
[in]	lrblok	The structure blok to initialize. Must be allocated before.
[in]	ws	The workspace associated with the data that will be used for initialize lrblok.

cpucblk_zfillin_fr()

static void cpucblk_zfillin_fr ( pastix_coefside_t  side, const SolverMatrix *  solvmtx, const pastix_bcsc_t *  bcsc, pastix_int_t  itercblk  )

inlinestatic

Initialize the full-rank coeftab structure from the internat bcsc.

Parameters

[in]	side	Define which side of the matrix must be initialized. PastixLCoef if lower part only PastixUCoef if upper part only PastixLUCoef if both sides.
[in]	solvmtx	PaStiX structure to store numerical data and flags
[in]	bcsc	The internal bcsc structure that hold the graph with permutation stored by cblk.
[in]	itercblk	The index of the cblk to fill in both bcsc and solvmtx structures.
