- Object → Curve → NonlinearCurve → ExponentialCurve
Remarks
Use the ExponentialCurve class to represent an exponential curve that can be used in non-linear least squares fitting. Each term in the sum is of the form a*Math.Exp(-b*x).
.
This type of curve is sometimes called a multi-exponential curve. For details on how to fit a curve of this type, see the NonlinearCurveFitter class.
