NAME
SLARGV  generates a vector of real plane rotations, determined by elements of the real vectors x and y
SYNOPSIS
 SUBROUTINE SLARGV(

N, X, INCX, Y, INCY, C, INCC )

INTEGER
INCC, INCX, INCY, N

REAL
C( * ), X( * ), Y( * )
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 )
ARGUMENTS
 N (input) INTEGER

The number of plane rotations to be generated.
 X (input/output) REAL array,

dimension (1+(N1)*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+(N1)*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+(N1)*INCC)

The cosines of the plane rotations.
 INCC (input) INTEGER

The increment between elements of C. INCC > 0.
