I started contributing to GNU Octave during [[Summer of Code#GSoC 2013|GSoC 2013]] as student and worked on incomplete factorizations (read my [http://siko1056-gsoc.blogspot.com/ blog]).

During my studies I specialized on software systems and communication networks and discovered a passion for computer arithmetic and algorithms, which will now be topic of my master thesis. I speak German (native), English (fluent) and Spanish (basic).
* My intention to participate in the GSoC 2013 is to work on a software project that can be part of my master thesis, which I start now in April. Till now I haven't participated in any GSoC and this year will be my last chance to do so.
* The choice for Octave came during the planning of my thesis schedule. My master thesis will deal with accurate fast scalar products and matrix-vector products for big sparse linear systems, usually coined to be called with MATLAB's MEX-Interface. But I prefer to use software where I can read the source code of how something is done, rather than a sparse documentation. So don't be afraid to disapprove my application, I'll stick to Octave.

Since I got to know MATLAB in my first semester, I also got to know about Octave and other numerical software environments.

** Do you like to discuss changes intensively and not start coding until you know what you want to do?
** Do you like to code a proof of concept to 'see how it turns out', modifying that and taking the risk of having work thrown away if it doesn't match what the project or original proponent had in mind?

* Please provide a rough estimated timeline for your work on the task. ''This should include the GSoC midterms and personal commitments like exams or vacation ("non-coding time"). Optionally include two or three milestones you expect.''

This is Kai Torben Ohlhus (a.k.a. siko1056 on Discourse and alike). I started contributing to GNU Octave during GSoC 2013 as student and worked on incomplete factorizations (read my blog). The project was completed in GSoC 2014 by Eduardo.

Since 2013, I continuously support the development of "core" Octave and maintain parts of the Octave Project Infrastructure:
