CSROT
Purpose:
!> !> CSROT applies a plane rotation, where the cos and sin (c and s) are real !> and the vectors cx and cy are complex. !> jack dongarra, linpack, 3/11/78. !>
Parameters
N
!> N is INTEGER !> On entry, N specifies the order of the vectors cx and cy. !> N must be at least zero. !>
CX
!> CX is COMPLEX array, dimension at least !> ( 1 + ( N - 1 )*abs( INCX ) ). !> Before entry, the incremented array CX must contain the n !> element vector cx. On exit, CX is overwritten by the updated !> vector cx. !>
INCX
!> INCX is INTEGER !> On entry, INCX specifies the increment for the elements of !> CX. INCX must not be zero. !>
CY
!> CY is COMPLEX array, dimension at least !> ( 1 + ( N - 1 )*abs( INCY ) ). !> Before entry, the incremented array CY must contain the n !> element vector cy. On exit, CY is overwritten by the updated !> vector cy. !>
INCY
!> INCY is INTEGER !> On entry, INCY specifies the increment for the elements of !> CY. INCY must not be zero. !>
C
!> C is REAL !> On entry, C specifies the cosine, cos. !>
S
!> S is REAL !> On entry, S specifies the sine, sin. !>
