title: Exchange subplots in figure
body: <p>I create a figure containing 4 subplots like:</p>
  
  <pre><code>y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
  fig = figure
  for i = 1 : 4
      h(i) = subplot(1,4,i)
      bar(y)
  end
  </code></pre>
  
  <p>Now I would like to exchange the order of the subplots. For example the first subplot should go in the last column (4th) and the 2nd subplot should exchange with the 3rd.</p>
  
  <p>Is it doable without generating again the figure?</p>
