One-Dimensional Complex Continuous Wavelet Analysis

This section takes you through the features of complex continuous wavelet analysis using the MATLAB Wavelet Toolbox and focuses on the differences between the real and complex continuous analysis.

You can refer to the section One-Dimensional Continuous Wavelet Analysis if you want to learn how to

• Zoom in on detail
• Display coefficients in normal or absolute mode
• Choose the scales at which the analysis is performed
• Switch from scale to pseudo-frequency information
• Exchange signal and coefficient information between the disk and the graphical tools

The Wavelet Toolbox requires only one function for complex continuous wavelet analysis of a real valued signal: 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 complex continuous wavelet transform of a signal
• Produce plots of the coefficients

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