DOUBLE PRECISION array, dimension (LDB,M)
          If (BPAR(1) = .FALSE.), then the leading N-by-M part of
          this array contains the matrix B of the factored form (I)
          of G. Otherwise, B is used as workspace.

  LDB     INTEGER
          The leading dimension of array B.  LDB &gt;= N.

  C       (output) DOUBLE PRECISION array, dimension (LDC,N)
          If (BPAR(4) = .FALSE.), then the leading P-by-N part of
          this array contains the matrix C of the factored form (II)
