GaussianCurve Class

Represents a Gaussian 'bell' curve that can be used for a non-linear regression calculation.

Definition

Namespace: Numerics.NET.Curves.Nonlinear
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.4
C# 
public class GaussianCurve : NonlinearCurve
Inheritance
Object  →  Curve  →  NonlinearCurve  →  GaussianCurve

Remarks

Use the GaussianCurve class to represent a four-parameter Gaussian curve with the characteristic 'bell' shape. This curve is used to fit data that contains a peak. The peak is less pronounced than that of the Lorentz curve.

.

For details on how to fit a curve of this type, see the NonlinearCurveFitter class.

Constructors

GaussianCurve Constructs a new Gaussian curve.

Properties

Amplitude Gets or sets the width of the Gaussian curve.
Area Gets or sets the area of the Gaussian curve.
Center Gets or sets the center of the Gaussian curve.
Offset Gets or sets the offset of the Gaussian curve.
Parameters Gets the collection of parameters that determine the shape of this Curve.
(Inherited from Curve)
Width Gets or sets the width of the Gaussian curve.
