public Action<Vector<double>, Vector<double>, Vector<double>> HessianVectorProduct { get; set; }

Visual Basic

Public Property HessianVectorProduct As Action(Of Vector(Of Double), Vector(Of Double), Vector(Of Double))
	Get
	Set

C++/CLI

public:
property Action<Vector<double>^, Vector<double>^, Vector<double>^>^ HessianVectorProduct {
	Action<Vector<double>^, Vector<double>^, Vector<double>^>^ get ();
	void set (Action<Vector<double>^, Vector<double>^, Vector<double>^>^ value);
}

member HessianVectorProduct : Action<Vector<float>, Vector<float>, Vector<float>> with get, set

Property Value

Action<Vector<Double>, Vector<Double>, Vector<Double>>

Remarks

The arguments are the current point, input vector and output buffer. Fully overwrite the output. Use the original objective sign, including when maximizing. Buffers belong to the optimizer.
