I would like to perform a fit, where the value of one of the fit parameters depends on the value of another fit parameter. For example, lets say I have a functions that has two parameters, then what I would like to do is the following:
Int_t fixedValue = 2; fitFunction->SetParameter(0, 1.); fitFunction->FixParameter(1, fitFunction->GetParamter(0) + fixedValue);
Basically, if I know the value of
par = par + fixedValue. However, this is a much more simplified version of my actual situation, so I do not want to define
par = par + fixedValue in my user defined function, and I was wondering if I could obtain the same results by using the above block of code? Or, is there a better method to achieve what I want?
Thank you very much and any help is appreciated!
