clacrt(3F)

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

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

         INTEGER        INCX, INCY, N

         COMPLEX        C, S

         COMPLEX        CX( * ), CY( * )

PURPOSE
     CLACRT applies a plane rotation, where the cos and sin (C and S) are
     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 -S*X +
             C*Y.

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

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