Could I get some help defining the angular momentum commutators symbolicaly in Julia?
I’ve tried using SymbolicUtils @acrules to define Nx*Ny - Ny*Nx => im*Nz but then when I run Nx*Ny - Ny*Nx it returns zero. I also tried defining the syms as Matrices but that returns errors about lack of methods or unknown dimensions.
Does anyone know how to get this to work? Thanks in advance!
@acrules stands for “associative, commutative”. You’re trying to handle a non-commutative operation, so you can’t use
@acrules for this. Last I checked, it’s a bit hard to handle non-commutative operators still in Symbolics.jl (but maybe it’s better now, I’m not sure)
I would be very happy about a tutorial on how to implement simple, non-commutative algebra with
