Surface.Hessian Method

public virtual void Hessian(
	ReadOnlySpan<double> point,
	Span2D<double> result
)

Public Overridable Sub Hessian ( 
	point As ReadOnlySpan(Of Double),
	result As Span2D(Of Double)
)

public:
virtual void Hessian(
	ReadOnlySpan<double> point, 
	Span2D<double> result
)

abstract Hessian : 
        point : ReadOnlySpan<float> * 
        result : Span2D<float> -> unit 
override Hessian : 
        point : ReadOnlySpan<float> * 
        result : Span2D<float> -> unit 

Parameters

point  ReadOnlySpan<Double>

A read-only span representing the coordinates of the point.

result  Span2D<Double>

A 2D span to receive the Hessian matrix (dimension × dimension, symmetric).

The Hessian is a symmetric matrix of second-order partial derivatives.

The length of point must equal Dimension. The result must be a square matrix with dimensions equal to Dimension.

Not all surface types support Hessian computation. The default implementation throws NotSupportedException. This method will be implemented in Phase 2.
