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*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.

INCX

          INCX is INTEGER


           On entry, INCX specifies the increment for the elements of


           CX. INCX must not be zero.

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.

INCY

          INCY is INTEGER


           On entry, INCY specifies the increment for the elements of


           CY. INCY must not be zero.

C

          C is DOUBLE PRECISION


           On entry, C specifies the cosine, cos.

S

          S is DOUBLE PRECISION


           On entry, S specifies the sine, sin.
