# Function/Subroutine Documentation

## subroutine zlartv (integerN, complex*16, dimension( * )X, integerINCX, complex*16, dimension( * )Y, integerINCY, double precision, dimension( * )C, complex*16, dimension( * )S, integerINCC)

ZLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.
Purpose:
``` ZLARTV applies a vector of complex plane rotations with real cosines
to elements of the complex vectors x and y. For i = 1,2,...,n

( x(i) ) := (        c(i)   s(i) ) ( x(i) )
( y(i) )    ( -conjg(s(i))  c(i) ) ( y(i) )
```
Parameters:
N
```          N is INTEGER
The number of plane rotations to be applied.
```
X
```          X is COMPLEX*16 array, dimension (1+(N-1)*INCX)
The vector x.
```
INCX
```          INCX is INTEGER
The increment between elements of X. INCX > 0.
```
Y
```          Y is COMPLEX*16 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 COMPLEX*16 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.
```
