Permutation Class

Represents a permutation, a rearrangement of the elements of a set or collection.

Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3

public class Permutation

Visual Basic

Public Class Permutation

C++/CLI

public ref class Permutation

type Permutation = class end

Inheritance: Object → Permutation

Remarks

Use the Permutation class to represent any rearrangement of the elements of a set or collection.

Constructors

Permutation(Int32)	Constructs a new Permutation.
Permutation(Int32[])	Constructs a new permutation.

Properties

IsEven	Gets whether the permutation is composed of an even number of elementary permutations.
IsIdentity	Gets whether the permutation is the identity permutation.
Item	Gets the position of an element after applying the permutation.
Length	Gets the length of the permutation.

Methods

ApplyInPlace(Action<Int32, Int32>)	Applies the permutation by swapping elements.
ApplyInPlace(IPermutable)	Applies the permutation to the rows of a permutable object.
ApplyInPlace<T>(T[])	Applies the permutation to the components of an array.
ApplyInPlace<T>(IList<T>)	Applies the permutation to a list.
ApplyInPlace<T>(Span<T>)	Applies the permutation to a span.
ApplyInverseInPlace(IPermutable)	Applies the inverse permutation to the components of a vector.
ApplyInverseInPlace<T>(T[])	Applies the permutation to the components of an array.
ApplyInverseInPlace<T>(IList<T>)	Applies the inverse permutation to a list.
ApplyInverseInPlace<T>(Span<T>)	Applies the permutation to a span.
Compose	Returns the composition of two permutations.
CreateRandom	Creates a new random permutation of the specified length.
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetInverse	Returns the inverse of this Permutation.
GetType	Gets the Type of the current instance. (Inherited from Object)
Inverse	Returns the position of an element after applying the inverse permutation.
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
Swap	Applies an elementary permutation.
ToString	Returns a String representation of the permutation. (Overrides Object.ToString())
