Colin,

I'll second the endorsement of Sage; however, for teaching purposes, I would suggest Sage Math Cloud. It is a free, web-based version of Sage, and it does not require you or the students to install any software (besides a new-ish web browser). It also make sharing/collaborative work quite easy as well. I've used this a bit for demos, and it's great. The author William Stein is good at correcting bugs/issues very quickly.

Sage implements it's own Matrix and Vector classes, and the Vector class has a "column" method that returns a column vector (transpose).

For what it's worth, I agree with others about the benefits of avoiding a Matrix class in Numpy. In my experience, it certainly makes things cleaner in larger projects when I always use NDArray and just call the appropriate linear algebra functions (e.g. np.dot, etc) when that is context I need.

Anyway, just my two cents.

Thanks Alexander,

I'll look at Sage.

If you're interested in an interface like this, then I'd suggest creating a new package focused specifically on that (which might use numpy internally). There's really no advantage in glomming this into numpy proper.Sorry for taking this further off-topic, but I recently discovered an excellent SAGE package, <http://www.sagemath.org/>. While it's targeted audience includes math graduate students and research mathematicians, parts of it are accessible to schoolchildren. SAGE is written in Python and integrates a number of packages including numpy. I would highly recommend to anyone interested in using Python for education to take a look at SAGE.
