Rotate<T>(ILinearAlgebraOperations<T>, Int32, SpanSlice<T>, SpanSlice<T>, T, T)

Applies a plane rotation.

C# 
public static void Rotate<T>(
	this ILinearAlgebraOperations<T> operations,
	int n,
	SpanSlice<T> x,
	SpanSlice<T> y,
	T c,
	T s
)

Parameters

operations  ILinearAlgebraOperations<T>
 
n  Int32
 
x  SpanSlice<T>
 
y  SpanSlice<T>
 
c  T
 
s  T
 

Type Parameters

T

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ILinearAlgebraOperations<T>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Rotate<T, TStorage>(ILinearAlgebraOperations<T>, Int32, TStorage, TStorage, T, T)

Applies a Givens plane rotation.
C# 
public static void Rotate<T, TStorage>(
	this ILinearAlgebraOperations<T> operations,
	int n,
	TStorage x,
	TStorage y,
	T c,
	T s
)
where TStorage : Object, IStorageSlice<T>

Parameters

operations  ILinearAlgebraOperations<T>
The linear algebra operations instance used to perform the calculation.
n  Int32
The number of elements in the vectors x and y.
x  TStorage
A reference to a one-dimensional array containing the elements of the vector x.
y  TStorage
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
TStorage
