Figures


from the book

You can download here the figures of the book. Simply click on the figure to retrieve a pdf file with the caption.

You can also retrieve all the figure as a single zip file.

Figures from chapters 1 to 11 can be reproduced using the Wavelab Matlab toolbox. The Wavelab directory has a folder called WaveTour. It contains a subdirectory for each chapter WTCh01, WTCh02, ...) ; these subdirectories include all the files needed to reproduce the computational figures from chapters 1 to 11. Each directory has a demo file.

Many of the figures of the books (including most of the numerical experiments of chapters 12 and 13) can be obtained by going through the numerical tours.
