Interface IFitResult

All Known Implementing Classes:

FitResult

public interface IFitResult

Represents the result of the fit. Holds internal copies of fit parameter settings (set in IFitter) and the fitted function (clone of original function). The value of the parameters of the fitted function are obtained from the fitting.

Returns:

The array containing the fitted values.

fittedParameterNames

String[] fittedParameterNames()

Get the names of the fitted parameters (including fixed and constrained ones).
