Is there a function that lists all the available user-defined classes in MATLAB 7.8 (R2009a)?

I am trying to list all the user-defined classes in MATLAB 7.8 (R2009a). The only method I see is to inspect the MATLAB PATH; however this will not list the classes defined in self contained files. I would like to know if there is a function that will list all the user-defined classes in MATLAB.

There are no built-in functions to list all the user-defined classes in MATLAB 7.8 (R2009a).

As a workaround, to specifically deal with classes defined in self-contained files, perform the following steps:

1. Create a self-contained class in your directory

2. At the MATLAB command prompt execute:

s = what

The structure s contains information about @ type of directories and all the MATLAB program files are listed in the field s.m.

Assuming that, your class MATLAB file is listed at position 1, then executing the following code, is going to return 'false' for all classes and true for all regular MATLAB files.

str = s.m{1}

isempty(meta.class.fromName(str(1:end-2)))

Carry out this operation in all user directories on the MATLAB path as well as their sub-directories except the @ and + directories.
