Follow-up Comment #1, bug #46830 (project octave):
Looking at the top command while running, it's clear that Matlab is using all
CPUs for .* wheras Octave is using just one. There are 6 CPUs on my machine.
If I change the .* to a * (matrix multiply) then top shows all the CPUs are
being used and the performance is the same.
