Wavelet Toolbox

Using This Guide

If you are new to wavelet analysis and synthesis and need an overview of the concepts, read Chapter 1, Wavelets: A New Tool for Signal Analysis. It presents the main ideas without mathematical complexity.

After this you can refer to Chapter 2 and Chapter 5, for instructions on using the wavelet and wavelet packet analysis tools, respectively; Chapter 3, which discusses practical applications of wavelet analysis; and Chapter 4, which provides examples and a case study.

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

• Chapter 2 and Chapter 5, for instructions on using the wavelet and wavelet packet analysis tools, respectively.
• Chapter 6, for a discussion of the technical underpinnings of wavelet analysis.
• Chapter 7, for instructions on extending the Wavelet Toolbox by adding your own wavelets.

All toolbox users should look to the:

• Reference Guide, the complete online reference information about the Wavelet Toolbox command line functions,
• Appendix A, for more detailed information on using the many functions provided by the graphical tools,
• Appendix B, for more information on using object-oriented programming.

Caution

1. 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.
2. 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 need probably to insert some simple graphical commands in the example code.
