## Function/Subroutine Documentation

### subroutine zlartv (integer N, complex*16, dimension( * ) X, integer INCX, complex*16, dimension( * ) Y, integer INCY, double precision, dimension( * ) C, complex*16, dimension( * ) S, integer INCC)

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.```
