! Subroutine: mld_c_hierarchy_bld
! Version: complex
!
! 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.
! info - integer, output.
! Error code.
!
! amold - class(psb_c_base_sparse_mat), input, optional
! Mold for the inner format of matrices contained in the
! preconditioner
!
!
! vmold - class(psb_c_base_vect_type), input, optional
! Mold for the inner format of vectors contained in the
! preconditioner

! Subroutine: mld_s_ml_prec_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.
! info - integer, output.
! Error code.
!
! amold - class(psb_s_base_sparse_mat), input, optional
! Mold for the inner format of matrices contained in the

! Subroutine: mld_z_ml_prec_bld
! Version: complex
!
! 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_zspmat_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_zprec_type), input/output.
! The preconditioner data structure containing the local part
! of the preconditioner to be built.
! info - integer, output.
! Error code.
!
! amold - class(psb_z_base_sparse_mat), input, optional
! Mold for the inner format of matrices contained in the
! preconditioner
!
!
! vmold - class(psb_z_base_vect_type), input, optional
! Mold for the inner format of vectors contained in the
! preconditioner
!
