Did you look at the documentation? The matrices implemented have their elements in arbitrary commutative rings (well, not arbitrary, somebody has to implement them in Julia, of course, but they have a bunch). I think its fair to call that abstract algebra; I wouldn't it numeric. In my university, that's how we teach linear algebra to math majors but not to engineers, for example.
