ZDROT
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.
| [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. |
