I've programmed somewhat on and off in C++, but I've never worked on a project with a group or intended for public consumption. A couple years ago I wrote a Quadratic Number Field Sieve using gmp and that was the first significant piece of code I wrote in C++. A couple months ago I wrote a preprocessor for grounded Answer Set Programs that does something analogous to forward-checking to infer binary constraints. During this project I read "Effective C++" and some of "C++ Templates: The Complete Guide". I did extensive online browsing to understand C++-11 rvalue references and perfect forwarding (although I realize Octave doesn't use C++-11 so those won't be available). I also posted a lot of questions on Stack Overflow.<br /> | I've programmed somewhat on and off in C++, but I've never worked on a project with a group or intended for public consumption.

I use Octave a lot for minor tasks that come up in research. It's a wonderful tool and I love coming up with sneaky ways to vectorize bits of code. Sometimes I go on StackOverflow to look for "how do you vectorize x" questions just so I can answer them. Most of them are for Matlab though. I don't know why Octave isn't a more popular alternative.<br /> | I use Octave a lot for minor tasks that come up in research.

On the one hand, I confess my documentation was absolutely terrible where it existed at all (today I believe I could do much better, I've had practice explaining things more completely and simply as a TA for CMPUT 101 and tend to get fairly positive reviews), but also these students were almost always freshman who had only just taken their first CS class. My approach to indexing game-states relied heavily on dynamic programming as well as results from combinatorics and generating functions and most of these students had just taken freshman calculus and hadn't expected to be doing any math. | On the one hand, I confess my documentation was absolutely terrible where it existed at all (today I believe I could do much better, I've had practice explaining things more completely and simply as a TA for CMPUT 101 and tend to get fairly positive reviews), but also these students were almost always freshman who had only just taken their first CS class.

I made a minor change to the m-script for the issymmetric function | I made a minor change to the m-script for the issymmetric function. I also created a significant patch to the find-function which consolidates all the many implementations into one templatized function. This fixes a couple separate bugs/matlab incompatibilities (find(sparse(0,0)), find(sparse(0,1)) etc. all work the same, six or more return values doesn't cause Octave to crash). Additionally, I added a fourth parameter for specifying the desired dimension of the output vector: http://savannah.gnu.org/patch/?8386 | ||

Honestly, the sparse-indexing problem doesn't sound like something that will take up three full months to complete, but I acknowledge that I haven't done much work on the Octave source yet, and can't properly judge this. If it doesn't, there are certainly many other sparse matrix features that have yet to be implemented which I would enjoy working on. | Honestly, the sparse-indexing problem doesn't sound like something that will take up three full months to complete, but I acknowledge that I haven't done much work on the Octave source yet, and can't properly judge this.
