This is a minor issue (if it is an issue at all) but I just thought I
would mention it.
When working on chain complexes I need to use 0*0 and 0*n dimensional
matrices. FriCAS seems to handle the maths well as far as I can tell but
the OutputForm notation looks a bit strange. I would have expected 1,2
and 3 below to be notated: []. Is this notation deliberate:
(1) -> a : Matrix(Integer) := new(0,0,0)
(1)
Type: Matrix(Integer)
(2) -> b : Matrix(Integer) := new(1,0,0)
(2) ][
Type: Matrix(Integer)
(3) -> c : Matrix(Integer) := new(0,1,0)
(3)
Type: Matrix(Integer)
(4) -> d : Matrix(Integer) := new(1,1,0)
(4) [0]
Type: Matrix(Integer)
