!
|

! Subroutine: mld_c_hierarchy_bld
|
||||
! Version: real
|
||||
!
|
||||
! This routine builds the preconditioner according to the requirements made by
|
||||
! the user trough the subroutines mld_precinit and mld_precset.
|
||||
!
|
||||
! A multilevel preconditioner is regarded as an array of 'one-level' data structures,
|
||||
! each containing the part of the preconditioner associated to a certain level,
|
||||
! (for more details see the description of mld_Tonelev_type in mld_prec_type.f90).
|
||||
! The levels are numbered in increasing order starting from the finest one, i.e.
|
||||
! level 1 is the finest level. No transfer operators are associated to level 1.
|
||||
!
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_cspmat_type).
|
||||
! The sparse matrix structure containing the local part of the
|
||||
! matrix to be preconditioned.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of a.
|
||||
! p - type(mld_cprec_type), input/output.
|
||||
! The preconditioner data structure containing the local part
|
||||
! of the preconditioner to be built.

! Subroutine: mld_s_hierarchy_bld
|

! Version: real
|

!
|
||||
! This routine builds the preconditioner according to the requirements made by
|
||||
! the user trough the subroutines mld_precinit and mld_precset.
|
||||
!
|
||||
! A multilevel preconditioner is regarded as an array of 'one-level' data structures,
|
||||
! each containing the part of the preconditioner associated to a certain level,
|
||||
! (for more details see the description of mld_Tonelev_type in mld_prec_type.f90).
|
||||
! The levels are numbered in increasing order starting from the finest one, i.e.
|
||||
! level 1 is the finest level. No transfer operators are associated to level 1.
|
||||
!
|
||||
!
|
||||
! Arguments:
|

! a - type(psb_sspmat_type).

! The sparse matrix structure containing the local part of the
|
||||
! matrix to be preconditioned.
|
||||
! desc_a - type(psb_desc_type), input.
|
||||
! The communication descriptor of a.
|
||||
! p - type(mld_sprec_type), input/output.
|
||||
! The preconditioner data structure containing the local part
|

! of the preconditioner to be built.

! Subroutine: mld_z_hierarchy_bld

! Version: real

!
|

! This routine builds the preconditioner according to the requirements made by
|

! the user trough the subroutines mld_precinit and mld_precset.
|
||||
!
|
||||
! A multilevel preconditioner is regarded as an array of 'one-level' data structures,

! each containing the part of the preconditioner associated to a certain level,

! (for more details see the description of mld_Tonelev_type in mld_prec_type.f90).
|

! The levels are numbered in increasing order starting from the finest one, i.e.
|
||||
! level 1 is the finest level. No transfer operators are associated to level 1.
