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

  LDC     INTEGER
          The leading dimension of array C.  LDC &gt;= MAX(1,P).

  D       (input/output) DOUBLE PRECISION array, dimension (LDD,M)
