NAME    [Toc]    [Back]

     CLARGV - generate a vector	of complex plane rotations with	real cosines,
     determined	by elements of the complex vectors x and y

SYNOPSIS    [Toc]    [Back]

     SUBROUTINE	CLARGV(	N, X, INCX, Y, INCY, C,	INCC )

	 INTEGER	INCC, INCX, INCY, N

	 REAL		C( * )

	 COMPLEX	X( * ),	Y( * )

PURPOSE    [Toc]    [Back]

     CLARGV generates a	vector of complex plane	rotations with real cosines,
     determined	by elements of the complex vectors x and y.  For i = 1,2,...,n

	(	 c(i)	s(i) ) ( x(i) )	= ( a(i) )
	( -conjg(s(i))	c(i) ) ( y(i) )	= (   0	 )

ARGUMENTS    [Toc]    [Back]

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

     X	     (input/output) COMPLEX 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) COMPLEX 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.
