Running 2 counters in 1 for loop simultaneously

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

[felimon mina]

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?

Answer 1

[Voss]

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
