Modules
module	hecmw_precond_saamg_coarse
	Smoothed Aggregation AMG preconditioner : coarsest-level solver.

Functions/Subroutines
subroutine, public	hecmw_precond_saamg_coarse::hecmw_saamg_coarse_setup (Ac, symmetric, cs)
	Densify Ac and factor it: symmetric -> LDL^T (dsytrf), else -> LU (dgetrf, for a non-symmetric coarse operator). bcsr_to_dense yields the full matrix, so LU is correct for non-symmetric A (dsytrf would use only the lower triangle). More...
subroutine, public	hecmw_precond_saamg_coarse::hecmw_saamg_coarse_solve (cs, b, x)
	Solve Ac x = b using the stored LDL^T factors. More...
