! Subroutine: mld_zprecaply
! Version: complex
!
! This routine applies the preconditioner built by mld_zprecbld, i.e. it computes
!
! Y = op(M^(-1)) * X,
! where
! - M is the preconditioner,
! - op(M^(-1)) is M^(-1) or its transpose, according to the value of trans,
! - X and Y are vectors.
! This operation is performed at each iteration of a preconditioned Krylov solver.
!
!
! Arguments:
! prec - type(mld_zprec_type), input.
! The preconditioner data structure containing the local part
! of the preconditioner to be applied.
! x - complex(psb_dpk_), dimension(:), input.
! The local part of the vector X in Y = op(M^(-1)) * X.
! y - complex(psb_dpk_), dimension(:), output.
! The local part of the vector Y in Y = op(M^(-1)) * X.
! desc_data - type(psb_desc_type), input.
! The communication descriptor associated to the matrix to be
! preconditioned.
! info - integer, output.
! Error code.
! trans - character(len=1), optional.
! If trans='N','n' then op(M^(-1)) = M^(-1);
! if trans='T','t' then op(M^(-1)) = M^(-T) (transpose of M^(-1)).
! work - complex(psb_dpk_), dimension (:), optional, target.
! Workspace. Its size must be at
! least 4*psb_cd_get_local_cols(desc_data).

! File: mld_zprecaply.f90.
!
! Subroutine: mld_zprecaply1.
! Version: complex.
!
! Applies the preconditioner built by mld_zprecbld, i.e. computes
!
! X = op(M^(-1)) * X,
! where
! - M is the preconditioner,
! - op(M^(-1)) is M^(-1) or its transpose, according to the value of trans,
! - X is a vectors.
! This operation is performed at each iteration of a preconditioned Krylov solver.
!
! This routine differs from mld_zprecaply because the preconditioned vector X
! overwrites the original one.
!
!
! Arguments:
! prec - type(mld_zprec_type), input.
! The preconditioner data structure containing the local part
! of the preconditioner to be applied.
! x - complex(psb_dpk_), dimension(:), input/output.
! The local part of vector X in X := op(M^(-1)) * X.
! desc_data - type(psb_desc_type), input.
! The communication descriptor associated to the matrix to be
! preconditioned.
! info - integer, output.
! Error code.
! trans - character(len=1), optional.
! If trans='N','n' then op(M^(-1)) = M^(-1);
! if trans='T','t' then op(M^(-1)) = M^(-T) (transpose of M^(-1)).
