    Purpose   
    =======   

    ZLARTV applies a vector of complex plane rotations with real cosines   
    to elements of the complex vectors x and y. For i = 1,2,...,n   

       ( x(i) ) := (        c(i)   s(i) ) ( x(i) )   
       ( y(i) )    ( -conjg(s(i))  c(i) ) ( y(i) )   

    Arguments   
    =========   

    N       (input) INTEGER   
            The number of plane rotations to be applied.   

    X       (input/output) COMPLEX*16 array, dimension (1+(N-1)*INCX)   
            The vector x.   

    INCX    (input) INTEGER   
            The increment between elements of X. INCX > 0.   

    Y       (input/output) COMPLEX*16 array, dimension (1+(N-1)*INCY)   
            The vector y.   

    INCY    (input) INTEGER   
            The increment between elements of Y. INCY > 0.   

    C       (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)   
            The cosines of the plane rotations.   

    S       (input) COMPLEX*16 array, dimension (1+(N-1)*INCC)   
            The sines of the plane rotations.   

    INCC    (input) INTEGER   
            The increment between elements of C and S. INCC > 0.
