NAME

SLARGV - generate 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+(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.
