I have a for loop that runs through all of my 1,000 rows. The next step is to get this code to run exactly the same way but for each of the 10,000 columns. I don't know if there is a simple way to do this–I tried adding "for j=1:n_trials" but that didn't seem to work. Any help is appreciated. Thanks!
n_steps = 1000 n_trials = 10,000 x_pos = zeros(n_steps,n_trials);
for i=2:n_steps direction=rand; if direction < 0.3 x_pos(i) = x_pos(i-1)+1; elseif (0.3 < direction) && (direction < 0.5) x_pos(i)=x_pos(i-1)-1; else x_pos(i)=x_pos(i-1); end end
