Detailed Description

Model objects, which reproduce component of polynomial function.

Expression can be written like:

Ampl * x^nx * y^ny * z^nz * ...

The order of polynomial function should be sets up in constructor like:
TGo4FitModelPolynom *p1 = new TGo4FitModelPolynom("Pol1",orderx,ordery,orderz);

TGo4FitModelPolynom::TGo4FitModelPolynom
TGo4FitModelPolynom()
Default constructor.
Definition TGo4FitModelPolynom.cxx:20

or
TArrayD orders(5);

Orders[0] = 1.; Orders[1] = 0.; ...

TGo4FitModelPolynom *p2 = new TGo4FitModelPolynom("Pol2",Orders);

According to number of parameters in constructor TGo4FitModelPolynom has set of parameters "Order0", "Order1" and so on, representing polynom orders for axis x, y and so on correspondingly. By default, these parameters are fixed and not fitted in optimizations. To change this default behavior, use:

p1->FindPar("Order0")->SetFixed(kFALSE);

TGo4FitParameter::SetFixed

void SetFixed(Bool_t iFixed)

Set status of parameter fixed or not.

Definition TGo4FitParameter.h:86

TGo4FitParsList::FindPar

TGo4FitParameter * FindPar(const char *ParName)

Find parameter object with given name.

Definition TGo4FitParsList.h:73

TGo4FitModelPolynom class always has amplitude parameter, named "Ampl". It can be accessed by its name, for instance:

p1->FindPar("Ampl")->SetValue(1000.);

TGo4FitParameter::SetValue

void SetValue(Double_t iValue)

Set parameter value.

Definition TGo4FitParameter.h:66

or

p1->GetAmplitudePar("Ampl")->SetValue(1000.);

GetAmplitudePar() method can be used in other models classes only if they create amplitude parameters, otherwise method returns 0.
