Detailed Description

Model object, which uses ROOT TFormula class facility.

Any kind of one-line expression can be analyzed by TFormula object and evaluated for given set of axis values and set of parameters. TGo4FitModelFormula in constructor creates additional parameters with names "Par0", "Par1" and so on, which can be used in equation and can be optimized. Optionally amplitude parameters with name "Ampl" can be created. In constructor expression, number of additional parameters and using of amplitude parameter should be specified. Fort instance, equation with 3 parameters and amplitude:

TGo4FitModelFormula f = new TGo4FitModelFormula("Form","(x-Par0)</em>(y-Par1)*(z-Par2)", 3, kTRUE);
