Methods

Icon	Type	Description
	Clone()	Constructs an exact copy of this instance.
	Equals(Object)	Determines whether the specified Object is equal to the current Object.
	FillPartialDerivatives(Double, GeneralVector)	Fills a GeneralVector with the partial derivatives of the curve with respect to each of the curve parameters.
	Finalize()	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
	FindRoots()	Gets the set of X-coordinates where the curve crosses the X-axis.
	GetCurveFitter()	Returns a CurveFitter object that can be used to fit the curve to data.
	GetDerivative()	Returns a Curve that represents the derivative of this Curve.
	GetHashCode()	Serves as a hash function for a particular type.
	GetType()	Gets the Type of the current instance.
	Integral(Double, Double)	Gets the definite integral of the curve between the specified X-coordinates.
	MemberwiseClone()	Creates a shallow copy of the current Object.
	OnParameterChanged(Int32, Double)	Called after a Curve parameter has been changed.
	OnParameterChanging(Int32, Double)	Called before the value of a curve parameter is changed.
	SetInitialValues(Vector, Vector)	Sets the curve parameters to initial values based on the specified data.
	SlopeAt(Double)	Gets the slope of the curve at the specified X-coordinate.
	TangentAt(Double)	Gets the tangent Line to the curve at the specified X-coordinate.
	ToString()	Returns a String that represents the current Object.
	ValueAt(Double)	Gets the Y-value of the curve at the specified X-coordinate.

Constructors

Icon	Type	Description
	GaussianCurveNew()	Constructs a new Gaussian curve.

Properties

Icon	Type	Description
	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.
	Width	Gets or sets the width of the Gaussian curve.

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 LorentzCurve.

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