Of course it's all they "can do". They're merely a way of writing down linear maps for a given choice of bases.
- raverbashing 6y agoYes. Then they're a "different" object than a square matrix or a vector. My point is, the sub-algebra of all square matrices supports more operations than mixing matrices of different sizes.
