NearestScatterSurface.Gradient Method

Definition

Namespace: Numerics.NET.Curves.Surfaces
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.1.0

Overload List

Gradient(Vector<Double>)	Computes the gradient of the surface at the specified point.
Gradient(Double, Double)	Computes the gradient of a 2D surface at the specified point.
Gradient(ReadOnlySpan<Double>, Span<Double>)	Computes the gradient of the surface at the specified point.
Gradient(Vector<Double>, Vector<Double>)	Computes the gradient of the surface at the specified point.

Gradient(ReadOnlySpan<Double>, Span<Double>)

Computes the gradient of the surface at the specified point.

public override void Gradient(
	ReadOnlySpan<double> point,
	Span<double> result
)

Visual Basic

Public Overrides Sub Gradient ( 
	point As ReadOnlySpan(Of Double),
	result As Span(Of Double)
)

C++/CLI

public:
virtual void Gradient(
	ReadOnlySpan<double> point, 
	Span<double> result
) override

abstract Gradient : 
        point : ReadOnlySpan<float> * 
        result : Span<float> -> unit 
override Gradient : 
        point : ReadOnlySpan<float> * 
        result : Span<float> -> unit

Parameters

point ReadOnlySpan<Double>: A read-only span representing the coordinates of the point.
result Span<Double>: A span to receive the gradient vector.

Remarks

Since nearest-neighbor interpolation produces a piecewise constant function, the gradient is zero almost everywhere (except at measure-zero boundaries between regions).

This implementation returns a zero vector for all points.

Exceptions

ArgumentException

The length of point does not equal Dimension.

-or-

The length of result does not equal Dimension.
