  SCAL    (output) INTEGER array, dimension (N)
          On exit, if INFO = 0, the leading N elements of this array
          contain the scaling parameters for the eigenvalues of A.

  IWORK   INTEGER array, dimension (LIWORK)
          On exit, if INFO = 0, IWORK(1) returns the optimal LIWORK,
          and if IWARN &gt; N, the nonzero absolute values in IWORK(2),
          ..., IWORK(N+1) are indices of the possibly inaccurate
          eigenvalues, a
