We have

(%i1) matrix([0])^0; (%o1) matrix([1])

but

(%i2) 0^0; 0^0 has been generated -- an error.

Similarly, [0]^0 --> [1].

(%o1) disagrees with the user documentation for domxexpt. I think the code should be changed to match the documentation --- the matrix ^ xxx code in simpexpt should be changed to simply map the power function onto the matrix elements.

What about matrix([0])^^0? This currently gives matrix([1]). I'd think that <singular>^^0 would be just as undefined as 0^0.
