~TVirtualFitter()
Cleanup virtual fitter.
TVirtualFitter* Fitter(TObject *obj, Int_t maxpar)
Static function returning a pointer to the current fitter.
If the fitter does not exist, the default TFitter is created.
const char* GetDefaultFitter()
return the name of the default fitter
TVirtualFitter* GetFitter()
return the current Fitter
Int_t GetMaxIterations()
Return the maximum number of iterations
Double_t GetPrecision()
Return the fit relative precision
void SetDefaultFitter(const char *name)
set name of default fitter
void SetFitter(TVirtualFitter *fitter, Int_t maxpar)
Static function to set an alternative fitter
void SetFCN(void (*fcn)(Int_t &, Double_t *, Double_t &f, Double_t *, Int_t))
To set the address of the minimization objective function
called by the native compiler (see function below when called by CINT)
void SetFCN(void *fcn)
To set the address of the minimization objective function
this function is called by CINT instead of the function above
void SetMaxIterations(Int_t niter)
Set the maximum number of iterations
void SetPrecision(Double_t prec)
Set the fit relative precision
