ZLARTV  -  applie a vector of complex plane rotations with
       real cosines to elements of the complex vectors x and y


SYNOPSIS

       SUBROUTINE ZLARTV( N, X, INCX, Y, INCY, C, S, INCC )

           INTEGER        INCC, INCX, INCY, N

           DOUBLE         PRECISION C( * )

           COMPLEX*16     S( * ), X( * ), Y( * )


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
