ZROT(l) 								 )								   ZROT(l)

NAME
       ZROT - applie a plane rotation, where the cos (C) is real and the sin (S) is complex, and the vectors CX and CY are complex

SYNOPSIS
       SUBROUTINE ZROT( N, CX, INCX, CY, INCY, C, S )

	   INTEGER	INCX, INCY, N

	   DOUBLE	PRECISION C

	   COMPLEX*16	S

	   COMPLEX*16	CX( * ), CY( * )

PURPOSE
       ZROT applies a plane rotation, where the cos (C) is real and the sin (S) is complex, and the vectors CX and CY are complex.

ARGUMENTS
       N       (input) INTEGER
	       The number of elements in the vectors CX and CY.

       CX      (input/output) COMPLEX*16 array, dimension (N)
	       On input, the vector X.	On output, CX is overwritten with C*X + S*Y.

       INCX    (input) INTEGER
	       The increment between successive values of CY.  INCX <> 0.

       CY      (input/output) COMPLEX*16 array, dimension (N)
	       On input, the vector Y.	On output, CY is overwritten with -CONJG(S)*X + C*Y.

       INCY    (input) INTEGER
	       The increment between successive values of CY.  INCX <> 0.

       C       (input) DOUBLE PRECISION
	       S       (input) COMPLEX*16 C and S define a rotation [  C	  S  ] [ -conjg(S)   C	] where C*C + S*CONJG(S) = 1.0.
