Hello, I would like to alter my code so that every value for position is stored in a matrix rather than dispaying only the final value so I can plot them later. How would I write this out? Here's what I've got. Thanks!
position = 0;
tails = 0;
heads = 1;
for s = (1:1000)
x=randi([0 1]);
if x==tails
position = position-1;
elseif x==heads
position = position+1;
end
end

position = zeros(1,1000);
position(1)=0;
tails = 0;
heads = 1;
for s = 2:1000
x=randi([0 1]);
if x==tails
position(s) = position(s-1)-1;
elseif x==heads
position(s) = position(s-1)+1;
end
end

Hello Estevan,
Try this:
position = zeros(1,1000);
tails = 0;
heads = 1;
for s = (1:1000)
x=randi([0 1]);
if x==tails
position(s) = position(s)-1;
elseif x==heads
position(s) = position(s)+1;
end
end
