public override TriangularMatrix<T> ExtractUpperTriangle(
	MatrixDiagonal unitDiagonal = MatrixDiagonal.NonUnitDiagonal
)

Visual Basic

Public Overrides Function ExtractUpperTriangle ( 
	Optional unitDiagonal As MatrixDiagonal = MatrixDiagonal.NonUnitDiagonal
) As TriangularMatrix(Of T)

C++/CLI

public:
virtual TriangularMatrix<T>^ ExtractUpperTriangle(
	MatrixDiagonal unitDiagonal = MatrixDiagonal::NonUnitDiagonal
) override

abstract ExtractUpperTriangle : 
        ?unitDiagonal : MatrixDiagonal 
(* Defaults:
        let _unitDiagonal = defaultArg unitDiagonal MatrixDiagonal.NonUnitDiagonal
*)
-> TriangularMatrix<'T> 
override ExtractUpperTriangle : 
        ?unitDiagonal : MatrixDiagonal 
(* Defaults:
        let _unitDiagonal = defaultArg unitDiagonal MatrixDiagonal.NonUnitDiagonal
*)
-> TriangularMatrix<'T>

Parameters

unitDiagonal MatrixDiagonal (Optional): If true, the matrix is unit triangular. Only the elements below the diagonal in the matrix are considered. If false, the diagonal elements of the matrix are taken as the diagonal elements of the triangular matrix.

Return Value

TriangularMatrix<T>
A TriangularMatrix<T> whose elements are contained in the lower triangular portion of the matrix.

Exceptions
