#11 Software: A wavelet toolbox for Matlab

I would like to announce the availability of a wavelet toolbox for
Matlab that implements the following wavelet and wavelet packet

One- and two-dimensional (periodic) fast wavelet and wavelet
packet transforms and the best basis algorithm for wavelet packets.

An implementation of the fast matrix multiplication algorithm of
Beylkin, Coifman, and Rokhlin (Comm. Pure Applied Math 44(2), 1991)
for both wavelets and wavelet packets.

Various demonstrations on visualizing wavelets, signal
analysis, and the multiplication algorithm.

The programs in this toolbox are mostly intended for learning about
wavelets. The toolbox grew out of my desire to teach myself about
wavelets and now I feel it has matured to the point where it might
prove useful to others. I think some of the visualization tools and
demos are rather unique.

All comments, criticism, bug reports, etc. are certainly welcomed!

The programs and documentation (both in Postscript and online)
are available on the web at

System requirements: Matlab 5.1 or later and a compatible C-compiler.
