## Function/Subroutine Documentation

### subroutine slargv (integer N, real, dimension( * ) X, integer INCX, real, dimension( * ) Y, integer INCY, real, dimension( * ) C, integer INCC)

SLARGV generates a vector of plane rotations with real cosines and real sines.

Purpose:

``` SLARGV generates a vector of real plane rotations, determined by
elements of the real vectors x and y. For i = 1,2,...,n

(  c(i)  s(i) ) ( x(i) ) = ( a(i) )
( -s(i)  c(i) ) ( y(i) ) = (   0  )```
Parameters:

N

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

X

```          X is REAL array,
dimension (1+(N-1)*INCX)
On entry, the vector x.
On exit, x(i) is overwritten by a(i), for i = 1,...,n.```

INCX

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

Y

```          Y is REAL array,
dimension (1+(N-1)*INCY)
On entry, the vector y.
On exit, the sines of the plane rotations.```

INCY

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

C

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

INCC

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