! File: mld_zbaseprec_bld.f90
!
! Subroutine: mld_zbaseprec_bld
! Version: complex
!
! This routine builds a 'base preconditioner' related to a matrix A.
! In a multilevel framework, it is called by mld_mlprec_bld to build the
! base preconditioner at each level.
!
! Details on the base preconditioner to be built are stored in the iprcparm
! field of the base preconditioner data structure (for a description of this
! data structure see mld_prec_type.f90).
!
!
! Arguments:
! a - type(psb_zspmat_type).
! The sparse matrix structure containing the local part of the
! matrix A to be preconditioned.
! desc_a - type(psb_desc_type), input.
! The communication descriptor of a.
! p - type(mld_zbaseprec_type), input/output.
! The 'base preconditioner' data structure containing the local
! part of the preconditioner at the selected level.
! info - integer, output.
! Error code.
! upd - character, input, optional.
! If upd='F' then the base preconditioner is built from
! scratch; if upd=T' then the matrix to be preconditioned
! has the same sparsity pattern of a matrix that has been
! previously preconditioned, hence some information is reused
! in building the new preconditioner.
