NAME
DLARTV  applies 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+(N1)*INCX)
The vector x.
 INCX (input) INTEGER

The increment between elements of X. INCX > 0.
 Y (input/output) DOUBLE PRECISION array,

dimension (1+(N1)*INCY)
The vector y.
 INCY (input) INTEGER
