title: How to concat string + i?
body: <pre><code>for i=1:N
     f(i) = 'f'+i;
  end
  </code></pre>
  
  <p>gives an error in MatLab. What's the correct syntax to initialize an array with N strings of the pattern fi?</p>
  
  <p>It seems like even this is not working:</p>
  
  <pre><code>for i=1:4
    f(i) = 'f';
  end
  </code></pre>
