Wavelet Toolbox

Object-Oriented Programming

In the Wavelet Toolbox, some object-oriented programming features are used for wavelet packet tree structures.

You may want to skip this appendix, if you prefer to use the command line functions and graphical user interface (GUI) without knowing about the underlying objects and classes. But, it is useful for Save and Load actions where objects are involved.

These aspects, related to a minimal use, are described in Using Wavelet Packets, and in the reference pages for the corresponding functions.

This appendix lets you understand the objects used in the toolbox, use some functions that are not fully documented in the reference pages, and extend the toolbox functionality using the predefined tree structures and some object programming features.

Of course, it is helpful to be familiar with the basic MATLAB object-oriented language and terminology.

Sections include

• Short Description of Objects in the Toolbox
• Simple Use of Objects Through Four Examples
• Detailed Description of Objects in the Toolbox
• Advanced Use of Objects (which tells how to extend the toolbox with new objects through four examples)
