How to store values of iterations during a for loop?

I have the following problem, I have three for loops, and I need to store the number of iterations that correspond to the second for loop, to show its total during the execution of the main loop. For example:

% Initialization
for i = 1:npop % first loop / npop = 600
    (something
end

% Iterations
for it = 1:iters % Main loop / iters = 100
    (something)
    
    for l = 1:nc  % third loop / obj function evaluation / nc = 600
        (something)
    end
end

In the first loop npop = 600, in the second iters = 100 and in the third nc = 600. If anyone has experience what I am doing is a genetic algorithm in which I want to show the number of objective function evaluations.

Thanks in advance.

hello

if you use for loops , that means you execute the loop until the last iteration index , so the total number of iterations of the second for loop is already known (as you specifiy it)

if you would use while lopps that's a different story

Hi Yro,

Have a look at for loop documentation in MATLAB to know how it works.

Open this example in MATLAB command window to run and display values in each iteration.

openExample('matlab/ExecuteStatementsForSpecifiedValuesExample')

Hope this helps.
