tains the imaginary parts of the poles of
          the transfer function matrix G, stored in the same way as
          the poles.

  GAINS   (output) DOUBLE PRECISION array, dimension (LDGAIN,M)
          The leading P-by-M part of this array contains the gains
          of the transfer function matrix G. Specifically,
          GAINS(i,j) contains the gain of the transfer function
          G(i,j).

  LDGAIN  INTEGER
          The leading dimension of array GAINS.  LDGAIN &gt;= max(1,P).
