Dear Rooters, is it possible to retrieve TF1 precompiled function ("type C") from ROOT file? There's no problem with TF1 "class A" and "class B". But what I obtained with function f1int from $ROOTSYS/test/stress.root: root [1] TFile f("stress.root"); root [2] f1int.Print() f1int : Ndim= 0, Npar= 9, Noper= 0 Par 0 p0 = 224.9 Par 1 p1 = -2.92761 Par 2 p2 = 3.02638 Par 3 p3 = 134.141 Par 4 p4 = -0.0224946 Par 5 p5 = 0.496904 Par 6 p6 = 83.9318 Par 7 p7 = 4.00135 Par 8 p8 = 0.633848 TH1.Print Name= Func, Total sum= 0 root [8] f1int.Eval(1) (Double_t)0.000000000000e+00 root [9] f1int.Eval(100) (Double_t)0.000000000000e+00 root [10] f1int.Eval(-3.14) (Double_t)0.000000000000e+00 - it is zero everywhere. Best regards, Boris Polishchuk
