== Summary of activities ==
=== Opening keynote speaker: John W. Eaton ===
John (aka, jwe) gave us another update on GNU Octave's development in the last year. Things look good for Octave but we still need to improve the flow from users to contributors. The optimal way would be to get more core developers (i.e. people who update and improve the core of Octave's) however users can contribute in many ways, some ideas follow:
* Helping with the Wiki.
* Commenting on bugs/features in [https://savannah.gnu.org/projects/octave/ tracker].
* Maintaining/updating/contributing packages to [http://octave.sourceforge.net/ Octave-Forge].
* Organizing events (talks, courses, etc.).
* Donating.
Finally, we discussed a lot about economic sustainability of the project. How can people make money using GNU Octave without damaging/endangering its freedom? Do you know business models that could fit? How can we organize a pool of developers to offer support for companies wanting to use GNU Octave?

=== Octave overview===
As usual, and meant for the new comers, there was an overview of GNU Octave.
This is an ongoing collaborative effort initiated by Jordi at OctConf 2012,
it was modified and extended by Carlo who presented it in varios occations (including
[http://femtec2013.femhub.com/ FEMTEC2013]).

=== Octave in numerical methods courses ===
Paola Gervasio gave a presentation about how she and her colleagues ([http://mox.polimi.it/qs/ authors of several books])use Octave in their courses at the university. You cansee exmaples used for the classes and some interesting pedagogic techniques in the slides.
[http://www.ing.unibs.it/~gervasio/ Contact her] if you have questions!
*[http://wiki.octave.org/wiki/images/2/27/Slides_octconf_paola_gervasio.pdf Slides]
=== Teaching engineers with GNU Octave ===
[https://staff.ti.bfh.ch/sha1/ Andreas Stahel] from Biel, Switzerland gave a talk about teaching GNU Octave for Engineering. All his material (code, lecture notes, etc) is available for download, reuse, remix, reshare.
*[http://wiki.octave.org/wiki/images/4/4c/Slides_octconf_andreas_stahel.pdf Slides]
=== NCLab ===
Martin Novak and Martin Balek, from [http://www.nclab.com NCLab], showcased their product and commented in the technology their are develping to have a fully functional GNU Octave server online. We hope this guys manage to earn they coins respecting the Free software community. Good luck!
*[http://wiki.octave.org/wiki/images/a/ac/Slides_octconf_martin_novak.pdf Slides]
=== LTFAT and Octave ===
Realtime sound processing with GNU Octave? It seems that the Czech-Danish team of [http://ltfat.sourceforge.net/ LTFAT] formed by Zdenek Prusa and Peter L. Søndergaard believes it is possible and are working towards it. We will hear (pun!) a lot from them in the coming months.
Apart from that, LTFAT provides an implementation of wavelets for GNU Octave.
* [http://wiki.octave.org/wiki/images/d/d1/Slides_octconf_zdenek_prusa.pdf Slides]
=== FEM mash-up and Octave ===
[http://www.graduate-school-ce.de/index.php?id=481 S. Schöps] showed a mash-up of proprietary and libre (FOSS) software to solve 3D coupled electromagnetic problems.
*[http://www.schoeps.org/octconf_2013.pdf Slides]
=== JIT Compiler ===
L Y.H., the student who will follow up the work of Max Brister, presented the difficulties with changes in LLVM and the JIT compiler for Octave.
Apparently, a re-structuring of this part of Octave is imminent.
*[http://wiki.octave.org/wiki/images/a/a4/Slides_octconf_lyh.pdf Slides]
=== New sparse matrix format for Octave ===
[http://librsb.sourceforge.net/ Michele Martone]
presented his (soon to be released) Octave package for sparse matrices "sparsersb".
The package enables Octave users to transparently use the "librsb"
multithreaded sparse matrix library from Octave, gaining performance
in the application of sparse matrix-vector multiplication operations on
large matrices (e.g.: when applying iterative methods).
Early testing efforts are very welcome.
Code and information is already available on [http://librsb.sourceforge.net] .
* [http://wiki.octave.org/wiki/images/9/92/Slides_octconf_michele_martone.pdf Slides]
=== GSoC project: Incomplete factorization ===
In future releases incomplete [https://en.wikipedia.org/wiki/Incomplete_LU_factorization LU-] and [https://en.wikipedia.org/wiki/Incomplete_Cholesky_factorization Cholesky-]factorizations will be part of Octave. In a short presentation one of this years Google Summer of Code students [[User:Siko1056|Kai T. Ohlhus]] talked about the project progress.

=== Spectral Variational Integrators ===
This project may take off with the acceptance of Octave into the ESA summer of code in Space. Very interestign for people working in Mechanics and Control.
* [http://wiki.octave.org/wiki/images/2/29/Slides_octconf_roberto_porcu.pdf Slides]
=== Hardware and Octave ===
The Octave-Forge [[Instrument control]] package allows to interface Octave with hardware. [http://reslab.elis.ugent.be/drjpi Juan Pablo Carbajal] gave a very short demo on how to do serial communication with the [http://www.dwengo.org Dwengo] board. [http://www.dwengo.org/node/486 Here are the details], [http://youtu.be/d1If8XOL73c watch the video].
