Detailed Description

Model objects, which reproduce component of polynomial function.

Expession 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); 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 correspondently. By default, these parameters are fixed and not fitted in optimizations. To change this default behavior, use:

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

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

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

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.

Creates TGo4FitModelPolynom object with given name for n-dim case. An array of polynoms orders for appropriate axis should be specified. The size of array will be a dimensions size of polynom. But the n-dim polynom can be used for m-dim case. If n>m, orders for missing axis will be set 0. If n<m, only necessary orders will be used.
