! Subroutine: psb_dsprn
!    Reinit sparse matrix structure for psblas routines: on output the matrix 
!    is in the update state.
! 
! Arguments: 
!    a        - type(psb_d_sparse_mat).        The sparse matrix to be reinitiated.      
!    desc_a   - type(psb_desc_type).          The communication descriptor.
!    info     - integer.                        Return code.
!    clear    - logical, optional               Whether the coefficients should be zeroed
!                                               default .true.
