Parameters
[in]N
          N is INTEGER
           On entry, N specifies the order of the vectors cx and cy.
           N must be at least zero.
[in,out]CX
          CX is COMPLEX*16 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.
[in]INCX
          INCX is INTEGER
           On entry, INCX specifies the increment for the elements of
           CX. INCX must not be zero.
[in,out]CY
          CY is COMPLEX*16 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.
[in]INCY
          INCY is INTEGER
           On entry, INCY specifies the increment for the elements of
           CY. INCY must not be zero.
[in]C
          C is DOUBLE PRECISION
           On entry, C specifies the cosine, cos.
[in]S
          S is DOUBLE PRECISION
           On entry, S specifies the sine, sin.
