Question: Commutator of matrices

Is it just me that is being daft, or am I correct in ascerting that there does still not exist (even in Maple 17) a command for taking the commutator of two matrices?

As far as I can tell from the help pages, there exists only a commutator of vector fields (in the tensor package), and a commutator af algebraic quantities (in the Physics package).

Not having such a command for matrices is, of course, not critical, as it is very easily programmed, but I am just surprised, for something as fundamental as checking some representation of a Lie algebra, say, requires taking such commutators.

Please Wait...
