! Subroutine: psb_zhalom
! This subroutine performs the exchange of the halo elements in a
! distributed dense matrix between all the processes.
!
! Arguments:
! x - real,dimension(:,:). The local part of the dense matrix.
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. Return code
! alpha - complex(optional). Scale factor.
! jx - integer(optional). The starting column of the global matrix.
! ik - integer(optional). The number of columns to gather.
! work - complex(optional). Work area.
! tran - character(optional). Transpose exchange.
! mode - integer(optional). Communication mode (see Swapdata)
! data - integer Which index list in desc_a should be used
! to retrieve rows, default psb_comm_halo_
! psb_comm_halo_ use halo_index
! psb_comm_ext_ use ext_index
! psb_comm_ovrl_ use ovrl_index
! psb_comm_mov_ use ovr_mst_idx

! Subroutine: psb_zhalov
! This subroutine performs the exchange of the halo elements in a
! distributed dense vector between all the processes.
!
! Arguments:
! x - real,dimension(:). The local part of the dense vector.
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. Return code
! alpha - complex(optional). Scale factor.
! jx - integer(optional). The starting column of the global matrix.
! ik - integer(optional). The number of columns to gather.
! work - complex(optional). Work area.
! tran - character(optional). Transpose exchange.
! mode - integer(optional). Communication mode (see Swapdata)
! data - integer Which index list in desc_a should be used
! to retrieve rows, default psb_comm_halo_
! psb_comm_halo_ use halo_index
! psb_comm_ext_ use ext_index
! psb_comm_ovrl_ use ovrl_index
! psb_comm_mov_ use ovr_mst_idx
