Wavelet Toolbox

Using This Guide

New Users

If you are new to wavelet analysis and synthesis and need an overview of the concepts, read Wavelets: A New Tool for Signal Analysis. It presents the main ideas without mathematical complexity.

After this you can refer to Using Wavelets and Using Wavelet Packets for instructions on using the wavelet and wavelet packet analysis tools, respectively; Wavelet Applications,, which discusses practical applications of wavelet analysis; and Wavelets in Action: Examples and Case Studies,, which provides examples and a case study.

Experienced Users

If you have experience with signal analysis and wavelets, you may want to turn directly to

• Using Wavelets, and Using Wavelet Packets, for instructions on using the wavelet and wavelet packet analysis tools, respectively.
• Advanced Concepts, for a discussion of the technical underpinnings of wavelet analysis.
• Adding Your Own Wavelets, for instructions on extending the Wavelet Toolbox by adding your own wavelets.

All Users

All toolbox users should look to the

• Function Reference, the complete online reference information about the Wavelet Toolbox command line functions
• GUI Reference, for more detailed information on using the many functions provided by the graphical tools
• Object-Oriented Programming, for more information on using object-oriented programming

Caution

• The examples of this guide are generated using the Wavelet Toolbox with the DWT extension mode set to 'zpd' (for zero padding), except when it is explicitly mentioned. So if you want to obtain exactly the same numerical results, type dwtmode('zpd'), before to execute the example code.
• In most of the command line examples, figures are displayed. To clarify the presentation, the plotting commands are partially or completely omitted. So if you want to reproduce the displayed figures, you probably need to insert some simple graphical commands in the example code.
