How to save all runs in the while loop

I'm trying to figure out how to save every point in my while loop in order to graph it in the comet function. My code looks like:

n = 1
score = 0
while n < 100
    n = n + 1
    x = randi(2);
    if (x == 1)
        score = score + 1;
    elseif(x == 2)
        score = score - 1;
    end
end
comet(score)

All it currently does is show what score ends as and i what to plot every point before then as well. What should i change it to to make it keep and plot every prevouis score?

Try this:

allScores = zeros(99,1);
n = 1;
score = 0;
while n < 100
    x = randi(2);
    if (x == 1)
        score = score + 1;
    elseif(x == 2)
        score = score - 1;
    end
    allScores(n) = score;
    n = n + 1;
end
comet(allScores)

Given that before the loop starts the number of iterations is already known, a for loop would be a better choice:

score = 0;
allScores = zeros(99,1);
for n = 1:99
    x = randi(2);
    if x==1
        score = score + 1;
    elseif x==2
        score = score - 1;
    end
    allScores(n) = score;
end
comet(allScores)

It would also be easy to remove the if:

score = 0;
allScores = zeros(99,1);
for n = 1:99
    score = score + 1 - 2*randi(0:1);
    allScores(n) = score;
end
comet(allScores)
