Function Documentation

cpucblk_zcfillin_fr()

static int cpucblk_zcfillin_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.

Returns

0 on success, 1 in case of overflow during initialization.
