Hi Hermine,
If you use a CINT interpreted function or a compiled function, simply
specify your constant when returning the value of the function.
If you use a predefined formula, insert a parameter in the definition
of the function, eg
TF1 f3("f3","[0]*pol2(1)",-2,2)
f3.SetParameters(10,1,0,1)
f3.Draw()
