RedHat 9 (Linux i386) - man page for crot (redhat section l)

CROT(l) 					)					  CROT(l)

NAME
       CROT  - 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 CROT( N, CX, INCX, CY, INCY, C, S )

	   INTEGER	INCX, INCY, N

	   REAL 	C

	   COMPLEX	S

	   COMPLEX	CX( * ), CY( * )

PURPOSE
       CROT 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 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 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) REAL
	       S	(input)  COMPLEX C and S define a rotation [  C 	 S  ] [ -conjg(S)
	       C  ] where C*C + S*CONJG(S) = 1.0.
