In the Wavelet Toolbox™ software, 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.
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.
It is helpful to be familiar with the basic MATLAB® object-oriented language and terminology.
