Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.5.0

Overload List

GetSkewSymmetricView<T>(Matrix<T>, MatrixTriangle, ArrayMutability) Returns a view of a matrix interpreted as skew-symmetric (anti-symmetric).
GetSkewSymmetricView<T>(Matrix<T>, Int32, MatrixTriangle, ArrayMutability) Returns a view of a matrix interpreted as skew-symmetric (anti-symmetric) with an explicit size.

GetSkewSymmetricView<T>(Matrix<T>, MatrixTriangle, ArrayMutability)

Returns a view of a matrix interpreted as skew-symmetric (anti-symmetric).
C# 
public static Matrix<T> GetSkewSymmetricView<T>(
	Matrix<T> source,
	MatrixTriangle triangle = MatrixTriangle.Upper,
	ArrayMutability mutability = ArrayMutability.Inherit
)

Parameters

source  Matrix<T>
The source matrix.
triangle  MatrixTriangle  (Optional)
Specifies which triangle of source holds the authoritative values. The default is Upper.
mutability  ArrayMutability  (Optional)
The desired mutability of the view. Must not exceed the mutability of source. The default is Inherit.

Type Parameters

T
The element type of the matrix.

Return Value

Matrix<T>
A matrix view where element [i,j] is the negation of [j,i] from the stored triangle, and diagonal elements are zero.

Exceptions

ArgumentNullException

source is null.

InvalidOperationException

mutability is more permissive than the mutability of source.

GetSkewSymmetricView<T>(Matrix<T>, Int32, MatrixTriangle, ArrayMutability)

Returns a view of a matrix interpreted as skew-symmetric (anti-symmetric) with an explicit size.
C# 
public static Matrix<T> GetSkewSymmetricView<T>(
	Matrix<T> source,
	int size,
	MatrixTriangle triangle = MatrixTriangle.Upper,
	ArrayMutability mutability = ArrayMutability.Inherit
)

Parameters

source  Matrix<T>
The source matrix.
size  Int32
The number of rows and columns of the view. Must be between 0 and the smaller of the row count and column count of source (inclusive).
triangle  MatrixTriangle  (Optional)
Specifies which triangle of source holds the authoritative values. The default is Upper.
mutability  ArrayMutability  (Optional)
The desired mutability of the view. Must not exceed the mutability of source. The default is Inherit.

Type Parameters

T
The element type of the matrix.

Return Value

Matrix<T>
A size×size matrix view where element [i,j] is the negation of [j,i], and diagonal elements are zero.

Exceptions

ArgumentNullException

source is null.

ArgumentOutOfRangeException

size is less than 0 or greater than the smaller of the row count and column count of source.
