DoubleFunctionalDelegate(Int32, FuncDoubleVector, Double, Double) Constructor

Constructs a DoubleFunctionalDelegate object from the given delegate and uses the given central difference delta value for estimating the gradient using a central difference algorithm.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

C++

Copy

public DoubleFunctionalDelegate(
	int xDimension,
	Func<DoubleVector, double> functional,
	double gradientCenteralDiffDelta
)

Public Sub New ( 
	xDimension As Integer,
	functional As Func(Of DoubleVector, Double),
	gradientCenteralDiffDelta As Double
)

public:
DoubleFunctionalDelegate(
	int xDimension, 
	Func<DoubleVector^, double>^ functional, 
	double gradientCenteralDiffDelta
)

new : 
        xDimension : int * 
        functional : Func<DoubleVector, float> * 
        gradientCenteralDiffDelta : float -> DoubleFunctionalDelegate

Parameters

xDimension Int32: The dimension of the domain of the functional.
functional FuncDoubleVector, Double: The delegate for evaluating the functional.
gradientCenteralDiffDelta Double: Delta value used for approximating the gradient using a central difference algorithm. The centeral difference algorithm will be used to approximate the graidient if no gradient delegate is provided.
