Maria - for each of your two blocks of code, look at each line and ask yourself "what is different?" The part that is different will be controlled by your iterating parameter. The trick is finding the general term for the sequence (the part that is different for each of your subplots). In our case, the sequence is
code iteration code dependent upon k
============ ========= =========================
1:2:100 k = 1 ==> 1 + 0 * 100 : 2 : 1 * 100
101:2:200 k = 2 ==> 1 + 1 * 100 : 2 : 2 * 100
201:2:300 k = 3 ==> 1 + 2 * 100 : 2 : 3 : 100
...
k 1 + (k - 1) * 100 : 2 : k * 100
And so your code could become
ntrials=1:numel(NumKey);
for k = 1:10
subplot(10,1,k); % kth subplot
plot(ntrials((1 + (k-1)*100):2:k * 100), NumKey((1 + (k-1)*100):2:k * 100),'o');
hold on
plot(ntrials((2 + (k-1)*100):2:k * 100), NumKey((2 + (k-1)*100):2:k * 100),'*');
yticks([1 2 3 4]);
end
