d the
          N-by-N upper triangular part of the submatrix in the
          columns 2 to N+1 of this array contains the upper triangle
          of the upper right symmetric block G' or G'' of the scaled
          Hamiltonian matrix H' in (2) or H'' in (3), depending on
          the setting of JOBSCL.
          If JOBSCL = 'N', this array is not referenced.
