## Function/Subroutine Documentation

### subroutine dlartv (integerN, double precision, dimension( * )X, integerINCX, double precision, dimension( * )Y, integerINCY, double precision, dimension( * )C, double precision, dimension( * )S, integerINCC)

**DLARTV** applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors.

**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) )
```

**Parameters:**

*N*

```
N is INTEGER
The number of plane rotations to be applied.
```

*X*

```
X is DOUBLE PRECISION array,
dimension (1+(N-1)*INCX)
The vector x.
```

*INCX*

```
INCX is INTEGER
The increment between elements of X. INCX > 0.
```

*Y*

```
Y is DOUBLE PRECISION array,
dimension (1+(N-1)*INCY)
The vector y.
```

*INCY*

```
INCY is INTEGER
The increment between elements of Y. INCY > 0.
```

*C*

```
C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
```

*S*

```
S is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.
```

*INCC*

```
INCC is INTEGER
The increment between elements of C and S. INCC > 0.
```
