### NAME[Toc][Back]

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

### SYNOPSIS[Toc][Back]

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

INTEGER	INCC, INCX, INCY, N

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

### PURPOSE[Toc][Back]

```     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[Toc][Back]

```     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.
