! Subroutine: psb_zsprn
! Reinit sparse matrix structure for psblas routines: on output the matrix
! is in the update state.
!
! Arguments:
! a - type(psb_zspmat_type). 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.
