NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     SUBROUTINE	ZLACRT(	N, CX, INCX, CY, INCY, C, S )

	 INTEGER	INCX, INCY, N

	 COMPLEX*16	C, S

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

PURPOSE    [Toc]    [Back]

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

ARGUMENTS    [Toc]    [Back]

     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	-S*X +
	     C*Y.

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

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