I don't know what is more common. I learned it under the name
"matrix", not "weight". By "weight", I would understand that one just
gets a degree vector for the ring generators (as in "weighted
homogeneous"), for example a "weighted degree lexicographic order".
Anyway, it seems redundant to give both a string ("weight" or
"matrix") *and* a matrix.
So, this syntax is shorter and clearer:
sage: TermOrder(A)
Note that when we talk about the input syntax, we would certainly not
be able to solve the problem with the __add__ method that I mentioned
in a previous post. I think that problem can only be solved by
improving the internal representation of the order.
Cheers,
Simon
