Definition

Namespace: Numerics.NET.LinearAlgebra
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.1.5

SubtractOuterProduct(Matrix<T>)	Updates a symmetric matrix by subtracting the product of a matrix and its transpose.
SubtractOuterProduct(Vector<T>)	Updates a symmetric matrix with the outer product of a vector and its transpose.

Updates a symmetric matrix by subtracting the product of a matrix and its transpose.

public SymmetricMatrix<T> SubtractOuterProduct(
	Matrix<T> matrix
)

Visual Basic

Public Function SubtractOuterProduct ( 
	matrix As Matrix(Of T)
) As SymmetricMatrix(Of T)

C++/CLI

public:
SymmetricMatrix<T>^ SubtractOuterProduct(
	Matrix<T>^ matrix
)

member SubtractOuterProduct : 
        matrix : Matrix<'T> -> SymmetricMatrix<'T>
