          op(A) * inv(diag(C)) where C is a REAL vector.

ARGUMENTS

        TRANS   (input) CHARACTER*1
                Specifies the form of the system of equations:
                = 'N':  A * X = B     (No transpose)
                = 'T':  A**T * X = B  (Transpose)
                = 'C':  A**H * X = B  (Conjugate Transpose = Transpose)

        N       (input) INTEGER
                The number of linear equations, i.e., the order of the
                matrix A.  N >= 0.

        A       (input) COMPLEX array, dimension (LDA,N)
                On entry, the N-by-N matrix A

        LDA     (input) INTEGER
                The leading dimension of the array A.  LDA >= max(1,N).

        AF      (input) COMPLEX array, dimension (LDAF,N)
                The factors L and U from the factorization
                A = P*L*U as computed by CGETRF.

        LDAF    (input) INTEGER
                The leading dimension of the array AF.  LDAF >= max(1,N).

        IPIV    (input) INTEGER array, dimension (N)
                The pivot indices from the factorization A = P*L*U
                as computed by CGETRF; row i of the matrix was interchanged
                with row IPIV(i).

        C       (input) REAL array, dimension (N)
                The vector C in the formula op(A) * inv(diag(C)).

        CAPPLY  (input) LOGICAL
                If .TRUE. then access the vector C in the formula above.

        INFO    (output) INTEGER
                = 0:  Successful exit.
                i > 0:  The ith argument is invalid.

        WORK    (input) COMPLEX array, dimension (2*N).
                Workspace.

        RWORK   (input) REAL array, dimension (N).
                Workspace.
