Represents a function returning a real number that has a Vector as its argument.

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

Syntax

Visual Basic (Declaration)
Public Delegate Function MultivariateRealFunction ( _
	x As Vector _
) As Double
C#
public delegate double MultivariateRealFunction (
	Vector x
)
C++
public delegate double MultivariateRealFunction (
	Vector^ x
)

Parameters

x (Extreme.Mathematics.LinearAlgebra.Vector)
A Vector.

Return Value

A real number.

Remarks

Use a MultivariateRealFunction delegate to encapsulate the evaluation of a real function with one Vector argument.

Many calculations involve the repeated evaluation of one or more user-supplied functions. Numerical integration and differentiation and finding zeroes of functions are common examples. In the .NET framework, this functionality is implemented using delegates.
