Why?
We have the empty matrix already.
(3) -> m := matrix([]$List(List(Integer)))
(3)
Type:
Matrix(Integer)
(4) -> m+m
(4)
Type:
Matrix(Integer)
(5) -> n := matrix([[],[],[]]$List(List(Integer)))
++
||
(5) ||
||
++
Type:
Matrix(Integer)
Not that I think that is useful, but there is no clash to the current code.
