Maxima is an opensource Computer Algebra System based on the legendary Macsyma.

Maxima can manipulate a wide range of symbolic and numerical expressions. The system handles differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors.

Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions.

How to define some variables as non-commutative in Maxima

For example, I'd like to define x and y as non-commutative, and a and b as commutative (as usual). In other words, x y ≠ y x, a x = x a, a b = b a . Further, (x + a y) (x - a y) = x^2 + a (y x - x y) - a^2 y^2 . What is a code for defining x and…
