Introduction to Wavelet Analysis
Each example is followed by a discussion of the usefulness of wavelet analysis for the particular application area under consideration.
Use the graphical interface tools to follow along:
- From the MATLAB® command line, type
- Click on Wavelets 1-D (or another tool as appropriate).
- Load the sample analysis by selecting the appropriate submenu item from File
Example Analysis.
Feel free to explore on your own -- use the different options provided in the graphical interface to look at different components of the signal, to compress or de-noise the signal, to examine signal statistics, or to zoom in and out on different signal features.
If you want, try loading the corresponding MAT-file from the MATLAB command line, and use Wavelet Toolbox™ functions to further investigate the sample signals. The MAT-files are located in the directory toolbox/wavelet/wavedemo.
There are also other signals in the wavedemo directory that you can analyze on your own.
