  N       (input) INTEGER
          The order of the pencil a J B' J' B - b D. N = 2 or N = 4.

  B       (input) DOUBLE PRECISION array, dimension (LDB, N)
          The leading N-by-N part of this array must contain the
          non-trivial factor of the decomposition of the
          skew-Hamiltonian input matrix J B' J' B. The (2,1) block
          is not referenced.

  LDB     INTEGER
