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.

X = 0;

while (abs(X) < 3);

if(rand < 0.7)

X = X + 1;

disp('A');

else

X = X - 1;

disp('B');

end

end

X

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<0.7) % number of times A wins
Bwins = N - Awins % number of times B wins

Note X<0.7 is a vector of ones and zeros (true and false) with a 1 on each trial where a wins and a zero on each trial where A does not win (B wins). Summing X<0.7 just adds up the total times A wins.
