This is '''Kai Torben Ohlhus''' (a.k.a. '''siko1056''' on Discourse and alike). 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]). The project was completed in [[Summer of Code#GSoC 2014|GSoC 2014]] by [[User:Edu159 | Eduardo]].
* I'm '''Kai Torben Ohlhus''', a [http://www.tuhh.de/alt/tuhh/education/degree-courses/masters-programs/informatik-ingenieurwesen.html computer science and engineering] student in the final master semester from Hamburg, Germany. 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.

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:
