  (input/output) DOUBLE PRECISION array, dimension (LDA,N)
          On input, if JOBSCL &lt;&gt; 'N', the leading N-by-N part of
          this array must contain the upper left block A of the
          Hamiltonian matrix H in (1).
          On output, if JOBSCL &lt;&gt; 'N', the leading N-by-N part of
          this array contains the leading N-by-N part of the scaled
          Hamiltonian matrix H' in (2) or H'' in (3), depending on
          the setting of JOBSCL.
          If JOBSCL = 'N', this array i
