When I simulate a model over and over again, why do I get different execution time. For example, in the following code I am grabbing the simulation time and for my model I see a wide variation of simulation executed time [ varies from 0.70 to 1.01 min]. I am trying to understand where the randomness / variations is coming from?
for i = 1:100
ts = tic;
sim(mymodel)
tf = toc(ts);
end

What is in the model? Any random variables, network dependencies? Why does this matter?

Its a deterministic model and without any network dependencies.
This matters when you are doing millions of simulation.
