Adds the scaled product of a Matrix and a Vector to this Vector.

Namespace: Extreme.Mathematics.LinearAlgebra
Assembly: Extreme.Numerics (Extreme.Numerics)

Syntax

Visual Basic (Declaration)
Public Overridable Function Add ( _
	factor As Double, _
	matrix As Matrix, _
	vector As Vector _
) As Vector
C#
public virtual Vector Add (
	double factor,
	Matrix matrix,
	Vector vector
)
C++
public:
virtual Vector^ Add (
	double factor, 
	Matrix^ matrix, 
	Vector^ vector
)

Parameters

factor (System.Double)
The scale factor for the matrix-vector product.
matrix (Extreme.Mathematics.LinearAlgebra.Matrix)
A Matrix.
vector (Extreme.Mathematics.LinearAlgebra.Vector)
A Vector.

Return Value

A reference to this instance.

Remarks

Using this method is more efficient than evaluating the equivalent expression using overloaded operators. In the latter case, three intermediate vectors are created. This method doesn't create any intermediate vectors.

Exceptions
