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*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 |
(input) INTEGER
On entry, INCX specifies the increment for the elements of
CX. INCX must not be zero. Unchanged on exit. |
| CY |
(input) 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 |
(input) INTEGER
On entry, INCY specifies the increment for the elements of
CY. INCY must not be zero. Unchanged on exit. |
| C |
(input) DOUBLE PRECISION
On entry, C specifies the cosine, cos.
Unchanged on exit. |
| S |
(input) DOUBLE PRECISION
On entry, S specifies the sine, sin.
Unchanged on exit. |
