|Matlab Wavelet Toolbox
A wavelet toolbox for the Matlab language has been developed;
Prospective users are invited to send their email addresses
for further information on its availability;
Prospective users are also invited to submit their requests for
tools and user interface features to be included in the toolbox;
Here's the scoop:
In 1991, dismayed by the lack of published algorithms, pseudocode, or
easily-readable source code for wavelet transforms (with all due respect and
apologies to authors/users/aficionados of any of the C language routines which
may have been available!), I began a project to develop routines in Matlab to
perform wavelet transform analysis. This project resulted in a wavelet
toolbox and a tech report dated Aug 1991 and entitled "Wavelet Transform
Algorithms for Finite-Duration Discrete-Time Signals. I. Signal-End Effects",
which described the software and provided program listings. Although it was not
publicized over the networks, both the Matlab software and techreport
have been made available to those who have requested it.
Since then, the Matlab wavelet toolbox has grown significantly and now includes
a variety of different transforms and decompositions of relevance to the field
of wavelet-based signal and image processing. It has been completely upgraded
with the new Matlab Version 4.1 graphics and graphical user interface.
This wavelet toolbox will be presented and demo'd at the Matlab Users
Conference in October.
However, between now and then, I would like to make an effort to include any
additional tools and features suggested by prospective users.
Given the following goals that the Matlab wavelet toolbox should be
1) A comprehensive collection of transforms and decompositions rather than
focussed on a specific author's work or particular perspective of the field,
2) Useful for both exploratory data analysis as well as efficient computation in
routine automated tasks,
3) Useful for teaching in educational settings;
what would YOU want to be in the toolbox? What do YOU think should be the
absolute "must-have" transform tools and user interace features for a first
release of the software? What do YOU think should be the desirable
"it-would-be-nice" additions for a subsequent release?
This software will be supported, so even if you do not want to take the time to
email me your suggestions, you might want to just send me your email address to
be added to a mailing list for information about availability of the wavelet
toolbox, bug reports, bug fixes, etc.
Well, as they say,
Thanks for Your Support!
