ARGUMENTS
 N (input) INTEGER

On entry, N specifies the order of the vectors cx and cy.
N must be at least zero.
Unchanged on exit.
 CX (input) 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 (input) INTEGER

On entry, INCX specifies the increment for the elements of
CX. INCX must not be zero.
Unchanged on exit.
 CY (input) 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 (input) INTEGER

On entry, INCY specifies the increment for the elements of
CY. INCY must not be zero.
Unchanged on exit.
 C (input) REAL

On entry, C specifies the cosine, cos.
Unchanged on exit.
 S (input) REAL

On entry, S specifies the sine, sin.
Unchanged on exit.
