Purpose:

!>
!> CLACRT performs the operation
!>
!>    (  c  s )( x )  ==> ( x )
!>    ( -s  c )( y )      ( y )
!>
!> where c and s are complex and the vectors x and y are complex.
!> 

Parameters

[in]	N	!> N is INTEGER !> The number of elements in the vectors CX and CY. !>
[in,out]	CX	!> CX is COMPLEX array, dimension (N) !> On input, the vector x. !> On output, CX is overwritten with c*x + s*y. !>
[in]	INCX	!> INCX is INTEGER !> The increment between successive values of CX. INCX <> 0. !>
[in,out]	CY	!> CY is COMPLEX array, dimension (N) !> On input, the vector y. !> On output, CY is overwritten with -s*x + c*y. !>
[in]	INCY	!> INCY is INTEGER !> The increment between successive values of CY. INCY <> 0. !>
[in]	C	!> C is COMPLEX !>
[in]	S	!> S is COMPLEX !> C and S define the matrix !> [ C S ]. !> [ -S C ] !>
