The MATLAB Toolbox comes with an inline class. This class allows you to create an object rather than a one line function MATLAB file that is used for all the function functions such as fmin, fplot, fzero,etc. Any of the methods and the constructor of the inline class can be viewed in a text editor. The available methods can be determined with the METHODS command:
methods('inline')
Another good way to learn object oriented programming in MATLAB is to look at the 'sym' class in the Symbolic Toolbox and the 'lti','ss','tf','zpk' classes in the Control Systems Toolbox.
