Dear all,
As the following example shows, when writing polynomials with noncommutative
variables one has to specify that the symbols belong to the list of NC
variables:
ops := OVAR[A,B]
ncomm := XDPOLY(ops, Integer)
q : ncomm := 3*B::ops*A::ops
I just found out that doing the same in REDUCE is more pleasant, since one
can
tell the interpreter that some identifiers are to be treated as
noncommuting variables:
nc_setup({A,B});
A*B - B*A;
How could one achieve the same with FriCAS?
Thank you in advance.
Marduk
