ECISION array, dimension (LDB,M)
          On entry, the leading N-by-M part of this array must
          contain the input/state matrix of the system.
          On exit, the leading NQ-by-M part of this array contains
          the input/state matrix of the numerator factor Q of the
          right coprime factorization with inner denominator of G
          (see METHOD).

  LDB     INTEGER
          The leading dimension of array B.  LDB &gt;= MAX(1,N).

  C       (input/output) DOUBLE PRECISION array, dim
