Why is my modulus giving me an error: Index in position 1 exceeds array bounds (must not exceed 1).

Hi all, I am trying to figure out if my modulus is working properly - I am iterating through a 2D array that has 220 columns (=col), and want to extract mod(col,12)

for col = 1:size(AU,2)  %220 columns (with some months missing)
    mod = mod(col,12);
    if mod == 0
        mod = 12;
    end
    %1
end

After running this code on Livescript, these are the value that I get on my command window:

col = 2

mod = 1

So it seems that the code only iterated once and got stuck in the second iteration. And I get an error like this in my command window: Index in position 1 exceeds array bounds (must not exceed 1).

Could you pleae explain to me how to fix this issue so that I can iterate through all the 220 columns??

mod = mod(col,12);

After the first of those, mod is no longer a function because you have assigned a number to mod
