title: Remove only axis lines without affecting ticks and tick labels
body: <p>Is there a way to remove only the axis lines in the Matlab figure, without affecting ticks and tick labels.  </p>
  
  <p>I know that <code>box</code> toggles the upper and right axes lines and ticks and that works perfectly for me.<br>
  But my problem is that I want eliminate the bottom and left lines (only lines!) but keeping the ticks and tick labels.  </p>
  
  <p>Any tricks?</p>
