Hi I am a beginner of Octave. How do I install a package?
This is from FAQ in Octave-Forge
First you need to download the package, by going to the package web page and clicking download. Then start Octave and go to the directory where you placed the downloaded package using the cd command. Then type
pkg install package_file_name.tar.gz
where package_file_name.tar.gz is the file name of the package you downloaded.
After I followed this direction and typed pkg list, but it still responds "no packages installed" Where (which directory) do I download?
Thanks

Hello,
I'm a research student and one part of my research is to use an open source
tool such as octave to detect attacks on off line
files as Intrusion detection system....We have agreed to use Neural networking
for this problem...
Since I have no experiences in data mining and octave.... I have the following
questions :)
1) Does octave is capable of doing this job ? i.e using neural networking to
detect the off line attacks on a system ?
2) Is there any neural network/octave packets that can be installed on ubuntu
hardy from the apt-get ? any docs are welcomed..
3) Is there any on line documents that show you how to use this tool with
examples ( preferably neural network examples ) ?
I would like to thank any replies or any suggestions..
regards
Al

I don't know about your specific problem, so I can't comment there. As
to using Neural Nets with Octave, then there are several solutions.
* Octave-Forge (http://octave.sf.net) has the 'nnet' package which
contains functions for Feedforward Neural Nets. I've never used it,
so I can't comment on how to use it.
* Some years ago, I created an Octave binding to the FANN library,
which is a pretty good library for working with Neural Nets. My
binding is no longer maintained, so I'm not sure if it still
works. If you feel like trying, you can get it from
http://hauberg.org/wiki/doku.php?id=octave-fann
* You can use Bishop's Netlab from
http://www.ncrg.aston.ac.uk/netlab/index.php
I think most of this package works with Octave, but I haven't used
it that much, so I'm not sure. If I were to use Neural Nets (which
I doubt I would), then I think this would be the software I'd
choose.

Not secret, but not easy to find either. The wiki instructions at
http://wiki.octave.org/wiki.pl?OctaveForMac don't seem to mention the
octave-forge scripts. The download pages linked on http://
octave.sourceforge.net have binaries, but not source. If you follow
the "SVN" link to http://sourceforge.net/svn/?group_id=2888 , there
is some boilerplate generic checkout command, a warning that you
probably don't want _everything_, and --- aha! --- a smallish link to
"browse the repository". From here I can make myself a tarball from
another well-hidden link.
It's a far cry from e.g. octave proper, where a page called
"download" has a link in a colored box at the top of the page.
Cheers,
Rob

Thomas,
Thanks for posting the info. When I encounter problems building via
Fink I often thought it would be nice if your scripts were readily
available ... and they are! I'll be referencing them next time I have
problems.
Rob,
The contributers each follow their passions. There are many instances
where I find the approach of others not quite to my liking. My
solution (as is "Octave proper") is to do something about it myself.
I
agree it would be nice if Octave's documentation were a bit better. We
are fortunate that some new contributers have begun taking on this
task. However, there is still more work than can be easily handled by
them. If there is some specific you don't think is getting the
attention it deserves, please contribute. All Mac users (including
myself) would surely appreciate you effort!
Ben

Hi Ben,
If I had write access to the wiki, I would add a paragraph like
> The scripts used to build the octave-forge Octave.app can be found
> in <a href="">the sourceforge subversion
repository</a>.
to the section "Source-Compilation" of the page http://
wiki.octave.org/wiki.pl?OctaveForMac
Cheers,
Rob

The wiki certainly needs some work. For example this page below
indicates that editing is not restricted, but as there have been some
defacements, it obviously is not.
http://wiki.octave.org/wiki.pl?UserName
Perhaps David can give us some instruction on how to gain access.

Just ask for a password at address@hidden (the
Octave-Forge list), and Etienne will provide you with one.

Message-ID: <address@hidden>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi,
I have uploaded the compressed disc images *.dmg including Octave.app 3.0.3
for PPC Mac OS X and i386 Mac OS X to the SourceForge's server. You can get
it from http://octave.sourceforge.net. Please read the Readme.html file that
comes with the *.dmg about 'Installation', 'FAQ',
'Limitations', etc.
I'm also very happy to see more than 8.300 downloads over the past 3 months
for Octave.app 3.0.2. However, please don't forget that all this is quite a
lot of work and your help is still needed in the development and contribution
to the GNU Octave project.
Further, if you like GNU Octave then please also think about of making a
donation to the Octave Core Development team. A description can be found
at http://www.gnu.org/software/octave/funding.html.
Recent changes:
- the latest stable Octave 3.0.3 sources available have been used to build
these binaries,
- Gnuplot.app 4.2.3 can be found in the Extras directory of the *.dmg.
Again, please read the Readme.html file about 'Installation',
'Limitations', 'FAQ', etc. for Gnuplot.app of that
compressed disc image.
- the checksums of the *.dmg are
- MD5 (octave-3.0.3-ppc.dmg) = 29a95fcb883110f3bff3c7c3ac5996cd
- MD5 (octave-3.0.3-i386.dmg) = 04e5abb7419d24fef70ea4cf662f5c5d
*Note:*
- the 3.0.x Octave.app series will be the last series that *I* also can build
for PPC Mac OS X 10.3.x too. The new 3.2.x series needs a more modern system
and therefore requires Mac OS X 10.4.x or higher for both platforms.
Regards,
Thomas

Subject: matlab behaviour of gzip
To: address@hidden
Message-ID: <address@hidden>
Content-Type: text/plain; charset=ISO-8859-1
Hi,
could someone with access to matlab try what the gzip function produces for
these examples:
- prepare a few files in the shell:
mkdir ttt
mkdir ttt/bla
mkdir ttt/bla/blubb
touch ttt/bla/11
touch ttt/bla/22
touch ttt/bla/33
touch ttt/bla/blubb/44
mkdir ttt/zip
- then in matlab:
cd ttt
gzip("bla")
ls (or is it dir in matlab?)
gzip("bla", "zip")
ls zip
What I am interested in: where do the gzipped files 11.gz etc. end up in both
cases? Do all the .gz
files end up directly in the zip directory or is the directory hierarchy (bla
and bla/blubb)
reproduced under zip?
In octave gzip("bla") gives an error reproduces the directory
hierarchy in the zip directory. And
when gzip is called with out the target directory argument, it gives an error.
I would like to know,
what matlab does before trying to fix this bug.
thanks
Thorsten
