I have a bunch of matrices, with their dimension known, but their
elements are unknown. Could I just treat them as symbols but based on
matrix operation rules?

Something like (A+B*K*C)*(A+B1*K*C1).=A^2 + A*B1*K*C1 + B*K*C*A +
B*K*C*B1*K*C1 .

Thanks!

That won't work because Maple treats * as commutative and will rearrange
the order. You could use the &* operator, which is not commutative.
However, Maple doesn't have any routines to treat these as
symbolic matrices.

OK.... If Maple can let the user to define a class and attach a bunch
of operations, that would be solvable. Anyway, thank you very much!
