Description
The routine performs the following transformation
where c, s are complex scalars and x, y are complex vectors.
Input Parameters
- n
-
INTEGER. The number of elements in the vectors cx and cy (n≥ 0).
- cx, cy
-
COMPLEX for clacrt
DOUBLE COMPLEX for zlacrt
Arrays, dimension (n).
Contain input vectors x and y, respectively.
- incx
-
INTEGER. The increment between successive elements of cx.
- incy
-
INTEGER. The increment between successive elements of cy.
- c, s
-
COMPLEX for clacrt
DOUBLE COMPLEX for zlacrt
Complex scalars that define the transform matrix
Output Parameters
- cx
-
On exit, overwritten with c*x + s*y .
- cy
-
On exit, overwritten with -s*x + c*y .
