Overload List
Rotate<T>(Int32, ArraySlice<T>, ArraySlice<T>, T, T) | Applies a Givens plane rotation. |
Rotate<T>(Int32, ArraySlice<Complex<T>>, ArraySlice<Complex<T>>, T, T) | A plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex. |
Rotate<T>(Int32, ArraySlice<T>, ArraySlice<T>, T, T)
Applies a Givens plane rotation.
public static void Rotate<T>(
int n,
ArraySlice<T> x,
ArraySlice<T> y,
T c,
T s
)
Parameters
- n Int32
- The number of elements in the vectors x and y.
- x ArraySlice<T>
- A reference to a one-dimensional array containing the elements of the vector x.
- y ArraySlice<T>
- A reference to a one-dimensional array containing the elements of the vector y.
- c T
- The first rotation element, the cosine of the rotation angle.
- s T
- The second rotation element, the sine of the rotation angle.
Type Parameters
- T
Rotate<T>(Int32, ArraySlice<Complex<T>>, ArraySlice<Complex<T>>, T, T)
A plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex.
public static void Rotate<T>(
int n,
ArraySlice<Complex<T>> cx,
ArraySlice<Complex<T>> cy,
T c,
T s
)
Parameters
- n Int32
On entry, N specifies the order of the vectors cx and cy. N must be at least zero.
- cx ArraySlice<Complex<T>>
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.
On entry, INCX specifies the increment for the elements of CX. INCX must not be zero.
- cy ArraySlice<Complex<T>>
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.
On entry, INCY specifies the increment for the elements of CY. INCY must not be zero.
- c T
On entry, C specifies the cosine, cos.
- s T
On entry, S specifies the sine, sin.
Type Parameters
- T
