How do I get my code to run multiple times? My code looks as follows. My code shows X = 3 when A wins and X = -3 when B wins. I would like to get this code to run multiple times and see how many times A wins out of 10 or so matches.
You don't need a loop for this, just do something like the following N = 10 % number of trials X = rand(N,1) Awins = sum(X<0....
