Wavelet Toolbox

One-Dimensional Continuous Wavelet Analysis

This section takes you through the features of continuous wavelet analysis using the MATLAB Wavelet Toolbox.

The Wavelet Toolbox requires only one function for continuous wavelet analysis: cwt. You'll find full information about this function in its reference page.

In this section, you'll learn how to

• Load a signal
• Perform a continuous wavelet transform of a signal
• Produce a plot of the coefficients
• Produce a plot of coefficients at a given scale
• Produce a plot of local maxima of coefficients across scales
• Select the displayed plots
• Switch from scale to pseudo-frequency information
• Zoom in on detail
• Display coefficients in normal or absolute mode
• Choose the scales at which analysis is performed

Since you can perform analyses either from the command line or using the graphical interface tools, this section has subsections covering each method.

The final subsection discusses how to exchange signal and coefficient information between the disk and the graphical tools.
