Class MnUserParameterState

java.lang.Object

org.freehep.math.minuit.MnUserParameterState

public class MnUserParameterState
extends java.lang.Object

The class MnUserParameterState contains the MnUserParameters and the MnUserCovariance. It can be created on input by the user, or by MINUIT itself as user representable format of the result of the minimization.
