I’m pretty new to ROOT and i’m trying to code in the following, I was wondering if anyone could give me some guidance?
First of all, if I generate a histogram for a Gaussian could I then randomly pull out values off this histogram to use in another equation?
I want to plot an equation (or histogram i guess?) in the form of
S = (x/a)^2 (y^2 + z^2)/2b where a and b are constants and x,y,z are randomly generated from a Gaussian.
y and z should have values randomly generated from “theta” with a peak at 0 and a variance calculated elsewhere, I have tried;
TF1 * variance = new TF1 ("variance", "(13.6*13.6)//"); variance->SetParameter(0, 3); variance->SetParameter(1, 0.98); TF1 * theta = new TF1("theta", gaus(0,variance));
but keep getting errors saying “gaus(0,variance) is not defined”
x should also have values randomly generated in a similar manner but with a user inputted variance and peak.
If anyone could give me guidance on how to start I would be extremely thankful,
