title: "No appropriate method" error generated when calling new function using class-defined object
body: <p>I defined a class called "FilterCriteria" which has a bunch of function .m files (getAMask, getBMask, etc.) associated with it. When I create the FilterCriteria object and call the functions using it, I don't have any problems. However, recently I added another function (which, on a side note, is almost identical to another function that still works), and Matlab returns the error, "No appropriate method, property, or field getHMask for class FilterCriteria."</p>
  
  <p>I've searched online for this problem, but I can't find anything. The file getHMask.m is definitely in the correct folder, so I don't understand why Matlab seems to have such a problem finding it.</p>
  
  <p>Here's getHMask.m's header: </p>
  
  <pre><code>function mask = getHMask(object, quadrant, channel)
  </code></pre>
  
  <p>Any help would be greatly appreciated. Thanks in advance.</p>
