title: How to sort a cell array in Octave by a column of floats?
body: <p>I created a cell array in Octave.  Some columns contain floats, and some columns contain strings.  I am able to sort the cell array by a column of <em>strings</em> (say col #4), using this command:</p>
  
  <pre><code>sortrows (mycellarray, 4);
  </code></pre>
  
  <p>But if the column I want to sort by is a column of <em>floats</em>, then I get this error message:</p>
  
  <pre><code>error: sort: only cell arrays of character strings may be sorted
  </code></pre>
  
  <p>Does anyone know how to sort a cell array, by a column of floats?</p>
