I apologize for being late to the thread but I'd like to invite folks to take a look at cvalarray in the boost vault. I wrote this a few years ago and has been in active use in our organization for years now and I've seen it around the net-mostly in raytracing circles. (Actually, I've seen it referenced as boost::cvalarray because they obtained it from the vault) I basically accomplishes the "small fixed sized numeric array" requirement and can be used as base for small matrix class as well. There is an internal version here that also uses SIMD (intel) for the underlying operations. I asked for an interest check on the list many moons ago but I only seemed to get a lukewarm reception. In any case, it is complete, uses expression templates to eliminate temporaries, requires nothing outside of the language, is self-contained in one file, and is well tested. Unless there is heartburn with the interface or underlying implementation, It basically just needs to be boostified and integrated into the build system. Take a look and see if it either meets your needs or could be used as a jumping off point. Mike On Mon, 30 Mar 2009, troy d. straszheim wrote:

I guess I'll be a voice of dissent. I personally think a fixed 2d matrix is too easy. It seems all you would have to do is either use a flat boost::array of Rows * Columns or the like, and copy boost::array's interface. This is from someone who is programming a game and already made a 2d matrix class.
I do, however, think that a fixed-size n-dimensional matrix would be better for GSoC, and can see the value in that. It would be difficult, though, without varidic templates.
On the other hand, you're not going to mentor the student. A gsoc project that gets finished, reviewed and committed to trunk is 10x better than one coded and partially documented, dumped into the "here's what I wrote this summer" google code repo. How hard the project is to *code* is only a small part of the problem. The hard part is getting the tests written, learning the build system, writing thousands of emails like this one, writing docs, etc. GSOC is as much training for this process as it is learning to code new stuff.

I take it back, sorry if my tone was off there. Having read more of the thread, I agree with you...
