! Subroutine: psb_zspasb
! Assemble sparse matrix
!
! Parameters:
! a - type(<psb_zspmat_type>). The sparse matrix to be assembled
! desc_a - type(<psb_desc_type>). The communication descriptor.
! info - integer. return code.
! afmt - character(optional) The desired output storage format.
! upd - character(optional). How will the matrix be updated?
! psb_upd_srch_ Simple strategy
! psb_upd_perm_ Permutation(more memory)
! dupl - integer(optional). Duplicate coefficient handling:
! psb_dupl_ovwrt_ overwrite
! psb_dupl_add_ add
! psb_dupl_err_ raise an error.
!
