### NAME[Toc][Back]

```     SLARGV - generate a vector	of real	plane rotations, determined by
elements of the real vectors x and	y
```

### SYNOPSIS[Toc][Back]

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

INTEGER	INCC, INCX, INCY, N

REAL		C( * ),	X( * ),	Y( * )
```

### PURPOSE[Toc][Back]

```     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  )

```

### ARGUMENTS[Toc][Back]

```     N	     (input) INTEGER
The number	of plane rotations to be generated.

X	     (input/output) 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    (input) INTEGER
The increment between elements of X. INCX > 0.

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

INCY    (input) INTEGER
The increment between elements of Y. INCY > 0.

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

INCC    (input) INTEGER
The increment between elements of C. INCC > 0.
