    Purpose   

    =======   

    ZLACGV conjugates a complex vector of length N.   

    Arguments   

    =========   

    N       (input) INTEGER   

            The length of the vector X.  N >= 0.   

    X       (input/output) COMPLEX*16 array, dimension   

                           (1+(N-1)*abs(INCX))   

            On entry, the vector of length N to be conjugated.   

            On exit, X is overwritten with conjg(X).   

    INCX    (input) INTEGER   

            The spacing between successive elements of X.
