Apply plane rotation

Input

N

Number of elements of vector x.

 

 

C

REAL scalar.

 

 

S

REAL or COMPLEX scalar.

 

 

X

REAL or COMPLEX array, minimum length

 

 

(N - 1) x incx + 1.

 

 

INCX

Increment for the array x. A vector x having component

 

 

xi, i = 1,..., n, is stored in an array X() with increment

 

 

argument incx. If incx > 0 then xi is stored in

 

 

X (1 + (i - 1) x incx). If incx < 0 then xi is stored in

 

 

X (1 + (N - i) x incx). incx = 0 is an illegal value.

 

Y

REAL or COMPLEX array, minimum length

 

 

(N - 1) x incy + 1.

 

 

INCY

Increment for the array y. A vector y having component

 

 

yi, i = 1,..., n, is stored in an array Y() with increment

 

 

argument incy. If incy > 0 then yi is stored in

 

 

Y(1 + (i - 1) x incy). If incy < 0 then yiis stored in

 

 

Y(1 + (N - i) x incy). incy = 0 is an illegal value.

Output

X

The updated array replaces the input—The plane

 

 

rotation of input X.

 

 

Y

The updated array replaces the input—The plane

 

 

rotation of input Y.
