title: Is there a way to find all children of a Matlab class?
body: <p>The Matlab function <a href="http://mathworks.com/help/matlab/ref/superclasses.html?searchHighlight=superclasses"><code>superclasses</code></a> returns the names of all parents of a given class.</p>
  
  <p>Is there an equivalent to find all classes <em>derived</em> from a given class, <em>i.e.</em> children classes ? The function <a href="http://mathworks.com/help/matlab/ref/allchild.html?searchHighlight=allchild"><code>allchild</code></a> seems to be restricted to graphical handles.</p>
  
  <p>If not, what strategy could be adopted to get such a list ? Is brute force path scanning the only option ?</p>
  
  <p>Let's restrict ourselves to the classes in Matlab's path.</p>
