Functions
pastix_fixdbl_t	cpublok_zcompress (const pastix_lr_t *lowrank, pastix_int_t M, pastix_int_t N, pastix_lrblock_t *lrA)
	Compress a single block from full-rank to low-rank format.
pastix_int_t	cpucblk_zcompress (const SolverMatrix *solvmtx, pastix_coefside_t side, int max_ilulvl, SolverCblk *cblk)
	Compress a single column block from full-rank to low-rank format.
void	cpucblk_zuncompress (pastix_coefside_t side, SolverCblk *cblk)
	Uncompress a single column block from low-rank format to full-rank format.
void	cpucblk_zmemory (pastix_coefside_t side, const SolverMatrix *solvmtx, SolverCblk *cblk, pastix_int_t *orig, pastix_int_t *gain)
	Return the memory gain of the low-rank form over the full-rank form for a single column-block.
