title: How to save MATLAB classes to file
body: <p>I would like to load and save some objects instantiated from a classdef style class.
  I can use "save" and "load" when the objects exist in the workspace, but not outside.</p>
  
  <p>For example, if I have a class called manager, that needs to load and save different employee classes, the employee classes will not exist in the workspace.</p>
  
  <p>Do I need to write a custom save routine? Is there a way of leveraging the existing tools?</p>
