Returns a delegate that numerically evaluates the gradient of a multivariate function.

Definition

Namespace: Extreme.Mathematics
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C#
public static Func<Vector<double>, Vector<double>, Vector<double>> GetNumericalGradient(
	this Func<Vector<double>, double> function
)

Parameters

function  Func<Vector<Double>, Double>
A delegate that represents a multivariate function.

Return Value

Func<Vector<Double>, Vector<Double>, Vector<Double>>
A delegate that represents a multivariate function returning a vector in its second argument.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Vector<Double>, Double>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
