Thank You, Mark!!! I'm not really sure what you mean about "running
waveleb.m from the wavelab850 directory" - where did you stick wavelab
(or does that really matter)? Is these the results you got? I'm using
QtOctave (on Windows) which is a front end for Octave 3.0.0. When I
loaded wavepath.m and ran it, it didn't throw an error, but it didn't
report a success either. When I tried to "run a matlab script" I got
the error at the bottom. Next I will try Octave 3.0.1, and Octave on
openSuSE 11.0 and see if they give the same result. Patti

Thank You,

Not to split hairs, but it appears that WaveLab is written to work in
Matlab, but is not part of it. Inclusion of WaveLab (or some other
wavelet functionality) in Octave proper would offer additional utility
to the base system, but would come at some cost (size of the base
package, maintenance and support of WaveLab code, etc.). Is WaveLab
important enough to include in the core program? The commercial
alternative appears to think not...
This page is a bit dated, but may offer some helpful information.
http://wiki.octave.org/wiki.pl?WavelabOnOctave
Does that help any? Are there specific errors that you're encountering
while installing/using WaveLab in Octave?
Please note that I haven't used WaveLab, so I can't vouch for it's
Octave compatibility.
Thank you very much for the reply, Mark. You're right about WaveLab -
and it not being part of Matlab is why I thought adding it to Octave
would be almost a no-braner (i.e., free, high quality, and Matlab
compatable) way to add wavelets to Octave. Matlab has written its own
wavelet tool box and which couldn't be easily added to Octave. The
folks who wrote WaveLab are some of the heavyweights in the wavelet biz
so it's not inconsequential code.
I'm a working scientist (The Aerospace Corporation) and my reading of
the literature shows wavelets over the last decade have become at least
as important as Fourier spectral analysis. I think it's important to
get some wavelets onto Octave as soon as possible. (Even Scilab has a
wavelet toolkit, but I'm attracted to Octave because of the Matlab
syntax compatibility.) I guess if it could be got running (with online
help?) I could contribute to a wiki or help somehow in
maintaining/publishing? I currently contrib on a few packages for
SourceForge (bacula and apcupsd) and the sbarnin openSuSE repo.
I don't dispute the importance of wavelets, the quality of the WaveLab
code, or the reputation of its authors. I think all of these points
have significant merit: wavelets have garnered significant attention
across many disciples, WaveLab was developed and is still used despite
the existence of Matlab's wavelet toolbox, and the WaveLab developers
are prominent and highly respected in their field.
However, one must keep in mind that these are not sufficient reasons for
inclusion in Octave. Wavelets may be used often and by many, but
WaveLab is a large body of code to take on for functionality that many
(probably most) Octave users won't use. IMHO, it would be better suited
as an add-on package from Octave-Forge.
Licensing is a separate but perhaps more important issue. WaveLab is
released as "freeware", but I couldn't to find any license for the
release. The items I could find appear to have some elements of concern:
To paraphrase Wavelab850/Documentation/COPYING.m, redistribution is
permitted but the original work must be included in its entirety and the
original authors retain copyright on all redistributions, whether
verbatim or modified works.
And from the Introduction section of documentation available at
http://www-stat.stanford.edu/~wavelab/Wavelab_850/AboutWaveLab.pdf,
"The library is available free of charge over the Internet by WWW
access; instructions are given below. The material is, however,
copyrighted, so that advance permission is required for
any commercial use."
I am not a lawyer, but these terms seem to conflict with Octave's
license, the GNU GPL. Perhaps a "non-free" Octave-Forge package (like
Arpack and spline-gcvspl) would be be a possibility.
I've been trying to muck through WaveLabOnOctave, but I'm such an Octave
noob - sometimes an Octave guru can do in 5 minutes what would take a
noob a month (or more) to understand and implement.
I tinkered a bit with WavePath.m, the file that adds the WaveLab code to
your [Octave] path. I made two changes: (1) eliminated the dependence
on the "matlabroot" variable by simply requiring that you run the script
from the WaveLab directory, and (2) removed some strange markup that
existed in the original file. The modified WavePath.m is attached.
Executing this file seems to successfully add all of the WaveLab stuff
to the Octave path on my machine. I didn't try to compile the mex
files, but the documentation indicates that the functions should still
work, albeit more slowly. An attempt to run one of the demos failed, it
seems that the demo is graphically based and incompatible with Octave
graphics (at least with the gnuplot backend that I'm using). So the
demos may be unavailable to you, but the functions that actually perform
various analyses should be accessible.
Does this help any?
