Matrices over noncommutative rings #208

Open kalmarek opened 7 years ago

kalmarek commented 7 years ago

Algorithms for matrix spaces over non-commutative rings:

One solution would be to add another abstract type Group :> Ring :> CRing :> ... and write algorithms for Rings without assuming commutativity, while those (simpler/faster??) assuming commutativity should dispatch after CRings(Elems).

This is indeed the right way to do it. But we lack the mathematics for some of the operations. Addition, multiplication and simple things like that should be possible to do without any problems.

We now have non-commutative rings, so I'm changing the title to reflect the original problem that was being raised.
