giving values to array as a 3 variable combination

Good morning everyone. I have this code.

for thr = 0.2:0.2:2.4,           %for threshold
  for pol = 0.1:0.1:1.0,       %for politeness factor
    fileID=fopen('parameters.txt','w');
    fprintf (fileID,'%4.2f %4.2f\r\n', thr, pol);
    fclose(fileID);
    [status,cmdout]=dos('"C:\Program Files\TSS-Transport Simulation Systems\Aimsun 8.0.3 (R26859)\aconsole.exe" -script python_script_2.py dutch.ang');
    for indFile =1:12,
      report = dlmread(['Mobil_MOVEMENT_' num2str(indFile-1) '.txt']);
      times = report(:, 6);
      tt(i,j,indFile) = max(times) - min(times);
    end
    save('travelTime', 'tt');
    j = j + 1;
  end
  i = i + 1;
  j = 1;

I have a source code in C++ and it takes through this matlab script two values from the "parameters.txt".

I run the console through [status,cmdout] and for each combination of these parameters (pol,thr), I get some meausurements in the Mobil_MOVEMENT_.txt. However, what I have done is , to create many different of this txt. For example, Mobil_MOVEMENT_0, Mobil_MOVEMENT_1, Mobil_MOVEMENT_2 until Mobil_MOVEMENT_11.

What I want is for each of these .txt to get the minimum and maximum values and save them in a table tt: tt(i,j,indFile) = max(times) - min(times);

What doesn't work is that after the simulations finish, they create exactly the same results for all the combinations, which in my case are 130. I believe, they aren't taken probably by the table.

Could you help me, how to get them correctly?

Thank you
