MATLAB: Is it possible to implement a class with one MATLAB file for properties and others methods in a ‘@’ directory in MATLAB 7.6 (R2008a)

folderMATLABmcosoopprivate

I have a class called TestClass implemented in a classdef file "TestClass.m". However, the class has many methods and the classdef file is unreadable. I would like to implement some of these methods as separate MATLAB files in a directory named @TestClass.

It is possible for a classdef MATLAB file to be used in conjunction with a set of methods in a '@' directory provided that the classdef file "TestClass.m" is in the @TestClass directory.

If "TestClass.m" is in a separate directory on the MATLAB path, MATLAB 7.6 will no longer treat the MATLAB files in @TestClass as methods of TestClass, and they will not be accessible.

One way is via composition: (see http://en.wikipedia.org/wiki/Object_composition)

Let your two classes be class A and class B. Inside a property block of the class definition file for class A, include a variable, say bObj, that you intend to be an instance of class B. Then, in the constructor of class A, instantiate this instance of class B

 bOjb = B(...)

Assuming that method m() of class B is public, invoke it anywhere in class definition file for class A with

 bObj.m(...)

MATLAB: How to expose the methods of the MATLAB object-oriented class through a C++ shared library with the MATLAB Compiler

The ability to directly generate a C++ class from a MATLAB class is currently not available as of MATLAB Compiler R2013a.

As a workaround, it is possible to write wrapper function MATLAB files around each of your MATLAB class methods and compile these into a C++ library. The wrapper functions should be written in such a way that:

1) If necessary, instances of your class are instantiated when the functions are invoked

2) The instances are made global such that methods may be invoked on the same class instance across calls to the MATLAB wrapper functions from C++.

Additionally, you may also write a C++ class whose methods wrap around the exported functions of the library in order to instantiate, invoke, and destroy your MATLAB class instances as necessary.
