Hello, I am doing an assignment for class which is called "even and odds" . It is similar to rock paper scissors but easier. What I am having trouble on is count the wins for each player. Here is my code
totalgames = 100;
odd_wins = zeros(1,totalgames);
even_wins = zeros(1,totalgames);
Totalgames = [1:totalgames];
for i=1:totalgames
x1(i) = randi(1:2,1);
x2(i) = randi(1:2,1);
total = x1(i)+x2(i);
if (total == 3);
odd_wins(i) = odd_wins(i) + 1;
else
even_wins(i) = even_wins(i) + 1;
end
end
My goal is to have odd_wins and even_wins row vector to keep track of how many times they have one for example [1,1,1,2,3,4,4,4,5...etc]. But these vectors always return [0,0,0,1,0,1,1...etc] where 0 means it lost and 1 means it won. How can I make it so it adds one to the value before it? Thank you!

A simple solution:
totalgames = 100;
odd_wins = zeros(1,totalgames);
even_wins = zeros(1,totalgames);
%% special case for the first game
x1(1) = randi(2);
x2(1) = randi(2);
total = x1(1)+x2(1);
if (total == 3)
odd_wins(1) = 1;
else
even_wins(1) = 1;
end
for i=2:totalgames
x1(i) = randi(2);
x2(i) = randi(2);
total = x1(i)+x2(i);
if (total == 3)
odd_wins(i) = odd_wins(i-1) +1;
even_wins(i) = even_wins(i-1);
else
even_wins(i) = even_wins(i-1) + 1;
odd_wins(i) = odd_wins(i-1);
end
end
