JSFVirtualFit()
~JSFVirtualFit()
void Initialize() 
 Initialize Fitting.   User should set value to
   fNpar
   fNDF
 then set size of fA and fDD array by
   fA.ResizeTo(fNpar,1);
   fDD.ResizeTo(fNpar,fNpar);
Bool_t Fit() 
 Fitting class.
void Derivative(Double_t &chis, JSFDMatrix &grad, JSFDMatrix &second) #else void JSFVirtualFit::Derivative(Double_t &chis, TMatrixD &grad, TMatrixD &second) #endif
