% new command to improve readability of indexed for loops in code
enumerate = @(my_array) cell2mat(arrayfun(@(x,idx) struct("cargo",x,"idx",idx), my_array(:).', 1:numel(my_array(:).'),UniformOutput=false));

% SAMPLE CODE
clc
random_stuff = rand(1, 3)
column_list  = (33:37).'

for outer = enumerate(column_list)
    disp("Item Number " + string(outer.idx) +" contains the numer " + string(outer.cargo) + ".")

    for inner = enumerate(random_stuff)
        disp("    " + string(outer.idx) + ": random nr. " + string(inner.idx) + " is: " + string(inner.cargo) + ".")
    end
end
