Hello, I would like to fill a matrix but I have a problem in filling it, because I get some extra entries even though I have initialized my matrix to the required size. Please find the problematic loop bellow, and hope you can help, thank you.
year = 1;
i = 0;
Nbrtot = 6;
MyResults = zeros(Nbrtot, 1);
for l = 1:year
for nbrrepetiton = 0:l
for NoYes = [0 1]
for semester = [1 2]
i = i + 1;
MyResults(i) = i;
end
end
end
end
Note: using this code My matrix MyResults has 2 extra entries.

for l = 1:year % one iteration
for nbrrepetiton = 0:l % two iterations
for NoYes = [0 1] % two iterations
for semester = [1 2] % two iterations
Each nested loop multiplies the total iterations by its own number of iterations, so we get:
1x2x2x2 = 8
So we find that MATLAB is doing exactly what you told it to do: eight iterations in total. There is no reason to expect six iterations here.
