subclassing MException

Hi there,

is it possible to subclass MException?? I'm trying to mock a third party software and therefore i need an exception object with the property 'ExceptionObject', so that i can run some code like this:

try
  %some commands
catch exception
  disp(exception.ExceptionObject.Message);
end

when i just subclass MException, the creation of the object fails with the error message 'not enough input arguments'. I'm using two strings(identifier & message) as input arguments, and creating a 'normal' MException object with these two arguments works fine.

Does anybody know where this error could come from, or any other way to create a custom exception object?

cheers, steffen

There are a lot of places you can go wrong, and without the code, it is hard to guess...

classdef testclass < MException
  properties (Dependent = true)
    ExceptionObject;
  end
  methods
    function obj = testclass(varargin)
      obj = obj@MException(varargin{:});
    end
    function val = get.ExceptionObject(obj)
      val.message = obj.message;
    end
  end
end
