Functions
pastix_fixdbl_t	core_sfrfr2lr (core_slrmm_t *params, pastix_lrblock_t *AB, int *infomask, pastix_int_t Kmax)
	Perform the operation AB = op(A) * op(B), with A and B full-rank and AB low-rank.
pastix_fixdbl_t	core_sfrlr2lr (core_slrmm_t *params, pastix_lrblock_t *AB, int *infomask, pastix_int_t Brkmin)
	Perform the operation AB = op(A) * op(B), with A full-rank and B and AB low-rank.
pastix_fixdbl_t	core_slrfr2lr (core_slrmm_t *params, pastix_lrblock_t *AB, int *infomask, pastix_int_t Arkmin)
	Perform the operation AB = op(A) * op(B), with B full-rank and A and AB low-rank.
pastix_fixdbl_t	core_slrlr2lr (core_slrmm_t *params, pastix_lrblock_t *AB, int *infomask)
	Perform the operation AB = op(A) * op(B), with A, B, and AB low-rank.

Detailed Description

PaStiX low-rank kernel routines that form the product of two matrices A and B into a low-rank form for an update on a null or low-rank matrix.
