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

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

      INTEGER	     INCC, INCX, INCY, N

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

DESCRIPTION
  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.
