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.

       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.

       Parameters:
	   N

		     N is INTEGER
		     The number of elements in the vectors CX and CY.

	   CX

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

	   INCX

		     INCX is INTEGER
		     The increment between successive values of CY.  INCX <> 0.

	   CY

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

	   INCY

		     INCY is INTEGER
		     The increment between successive values of CY.  INCX <> 0.

	   C

		     C is DOUBLE PRECISION

	   S

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