title: use of strcat function
body: <p>I would like to check that I have </p>
  
  <pre><code>workingDir = C:\Users\~\Temp\workspace_folder;
   for i=1:2
   % do an action which generates folder C:\Users\~\Temp\workspace_folder_1 first iteration
   % and increment for each iteration
   x = strcat(workingDir,'_',i);
  end
  </code></pre>
  
  <p>it gives only </p>
  
  <p>x = C:\Users\~\Temp\workspace_folder_ , why do it doesn't print me the iteration value?
  I expected to have </p>
  
  <pre><code>C:\Users\~\Temp\workspace_folder_1
  C:\Users\~\Temp\workspace_folder_2
  </code></pre>
  
  <p>Thanks</p>
