Hi again,
a definition like
TFormula *g2 = new TFormula("g2","[3]*exp(-((x-[4]*.68)^2)/[5]^2)");
which has obviously three parameters, starting at index 3 returns, if
asked
for the number of paramters via
g2->GetNpar()
six parameters .
root [6] TFormula *g2 = new
TFormula("g2","[3]*exp(-((x-[4]*.68)^2)/[5]^2)");
root [7] g2->GetNpar()
(Int_t)6
is this correct ?
We are looking for a way to build one six-parametric function from two
three parametric functions an fit this to a histo. This was already a
topic in
Re: formula with multiple TFormula from T Auger
In our case it causes difficulties whenn fitting the six-apametrix
function.
Cheers,
Norbert
