SymmetricMatrix<T>.AddOuterProductInPlace Method

Definition

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

Overload List

AddOuterProductInPlace(Vector<T>)	Updates the matrix by adding the outer product of a vector with itself.
AddOuterProductInPlace(T, Vector<T>)	Updates the matrix by adding the scaled outer product of a vector with itself.
AddOuterProductInPlace(Vector<T>, Vector<T>)	Updates the matrix by adding the outer product of two vectors.
AddOuterProductInPlace(T, Vector<T>, Vector<T>)	Updates this symmetric matrix by adding the scaled outer product of two vectors.

AddOuterProductInPlace(T, Vector<T>, Vector<T>)

Updates this symmetric matrix by adding the scaled outer product of two vectors.

public override Matrix<T> AddOuterProductInPlace(
	T factor,
	Vector<T> left,
	Vector<T> right
)

Visual Basic

Public Overrides Function AddOuterProductInPlace ( 
	factor As T,
	left As Vector(Of T),
	right As Vector(Of T)
) As Matrix(Of T)

C++/CLI

public:
virtual Matrix<T>^ AddOuterProductInPlace(
	T factor, 
	Vector<T>^ left, 
	Vector<T>^ right
) override

abstract AddOuterProductInPlace : 
        factor : 'T * 
        left : Vector<'T> * 
        right : Vector<'T> -> Matrix<'T> 
override AddOuterProductInPlace : 
        factor : 'T * 
        left : Vector<'T> * 
        right : Vector<'T> -> Matrix<'T>

Parameters

factor T: The scale factor.
left Vector<T>: The first (column) vector.
right Vector<T>: The second (row) vector.

Return Value

Matrix<T>
A reference to this instance.

Remarks

For symmetric matrices, when left and right are the same vector, this uses the optimized level 2 BLAS routine DSYR. Otherwise, it falls back to the general implementation.
