DLARTV(l)					)					DLARTV(l)

NAME
       DLARTV - applie a vector of real plane rotations to elements of the real vectors x and y

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

	   INTEGER	  INCC, INCX, INCY, N

	   DOUBLE	  PRECISION C( * ), S( * ), X( * ), Y( * )

PURPOSE
       DLARTV  applies	a vector of real plane rotations to elements of the real vectors x and y.
       For i = 1,2,...,n
	  ( x(i) ) := (  c(i)  s(i) ) ( x(i) )
	  ( y(i) )    ( -s(i)  c(i) ) ( y(i) )

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

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

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

       Y       (input/output) DOUBLE PRECISION 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) DOUBLE PRECISION 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.
