I am trying to run a for loop that has 2 counters instead of one. Example
for i=1:2 j=0:12:12 ....
So, first iteration i=1 and j=0 second iteration i=2 and j=12

because you write j = 0:12:12 so you use a step by 12 , so if you use step by 1 , j = 0:1:12 it runs better

@felimon mina: What if they want j = 0:12:12 and not j = 0:1:12? Surely, j = 0:1:12 would not be better if the desired behavior was j = 0:12:12, right?

i_all = [1 2];
j_all = [0 12];
for idx = 1:numel(i_all)
i = i_all(idx);
j = j_all(idx);
% ...
end

Hi,
you just need to define j outside the loop. And then use it with i as index.
j = 0:12:12;
for i= 1:2
% Write your code here using j with i as subscript.
%for example x(i) = j(i);
end
