Re: [Maxima-discuss] Declaring a non-commutative variable?

[Stavros M. <mac...@al...>]

The multiplication operator "." denotes non-commutative multiplication;
a^^n == a . ... . a <n times>. There is a large number of global variables
controlling simplification of ".", all starting with "dot". The command [??
dot] will list them.

If you set dotscrules:true, then <scalar>.A and A.<scalar> simplify to
<scalar>*A. Numbers and constants are always scalar, and <number>.A always
simplifies to <number>*A (regardless of dotscrules). You can explicitly
declare variables scalar and nonscalar.
