PURPOSE

          ZLA_SYRCOND_X Computes the infinity norm condition number of
          op(A) * diag(X) where X is a COMPLEX*16 vector.

ARGUMENTS

        UPLO    (input) CHARACTER*1
                = 'U':  Upper triangle of A is stored;
                = 'L':  Lower triangle of A is stored.

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

        A       (input) COMPLEX*16 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*16 array, dimension (LDAF,N)
                The block diagonal matrix D and the multipliers used to
                obtain the factor U or L as computed by ZSYTRF.

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

        IPIV    (input) INTEGER array, dimension (N)
                Details of the interchanges and the block structure of D
                as determined by ZSYTRF.

        X       (input) COMPLEX*16 array, dimension (N)
                The vector X in the formula op(A) * diag(X).

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

        WORK    (input) COMPLEX*16 array, dimension (2*N).
                Workspace.

        RWORK   (input) DOUBLE PRECISION array, dimension (N).
