Follow-up Comment #4, bug #38466 (project octave):
In Octave, all "A op= B" operators are just syntactic sugar for "A = A op B",
so some can change the size of A:
octave:1> A = [1,2,3;4,5,6];
octave:2> B = [1,2;3,4;5,6];
octave:3> A *= B
A =
22 28
49 64
That's the expected result and makes sense given the simple rule that A op= B
is exactly the same as A = A op B.
