Follow-up Comment #6, bug #48736 (project octave):

Thanks for pointing out (anonymous) that the computation complexity of
division is higher.

Something is still funny. That is, .*= is still thrice as expensive as *=,
even when RHS is a scalar. Jordigh mused on irc that's probably because it's
(needlessly) going through some broadcasting in the former case.
