### NAME[Toc][Back]

ZLARTV - applie a vector of complex plane rotations with real cosines to
elements of the complex vectors x and y

### SYNOPSIS[Toc][Back]

SUBROUTINE	ZLARTV(	N, X, INCX, Y, INCY, C,	S, INCC	)

INTEGER	INCC, INCX, INCY, N

DOUBLE		PRECISION C( * )

COMPLEX*16	S( * ),	X( * ),	Y( * )

### PURPOSE[Toc][Back]

ZLARTV applies a vector of	complex	plane rotations	with real cosines to
elements of the complex vectors x and y. For i = 1,2,...,n

( x(i) ) := (	     c(i)   s(i) ) ( x(i) )
( y(i) )    ( -conjg(s(i))  c(i) ) ( y(i) )

### ARGUMENTS[Toc][Back]

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

X	     (input/output) COMPLEX*16 array, dimension	(1+(N-1)*INCX)
The vector	x.

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

Y	     (input/output) COMPLEX*16 array, dimension	(1+(N-1)*INCY)
The vector	y.

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

C	     (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The cosines of the	plane rotations.

S	     (input) COMPLEX*16	array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.

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