! Subroutine: mld_dcoarse_bld
|

! Version: real
|
||||
!
|
||||
! This routine builds the matrix associated to the current level of the
|
||||
! multilevel preconditioner from the matrix associated to the previous level,
|
||||
! by using a smoothed aggregation technique (therefore, it also builds the
|
||||
! prolongation and restriction operators mapping the current level to the
|
||||
! previous one and vice versa). Then the routine builds the base preconditioner
|
||||
! at the current level.
|
||||
! The current level is regarded as the coarse one, while the previous as
|
||||
! the fine one. This is in agreement with the fact that the routine is called,
|
||||
! by mld_mlprec_bld, only on levels >=2.
