Hello,
I would like to define a TF1 with a step function inside, like:
TF1 *f = new TF1(“f”, " sin(x)*theta(x-2)", -10, 10);
where theta is the typical step function: it returns 0 if (x-2)<0 and it returns 1 if (x-2)>0.
Unfortunately I have not found any step function in TMath neither in other libraries, but only TMath::Floor() and TMath:.Ceil().
Could you help me?
Many thanks
