Follow-up Comment #5, bug #42735 (project octave):
Ok, I've done some tests with three classdef classes: A and B are unrelated.
C is a subclass of A. Attached below.
Here is what Matlab 2015b does:
>> a = A(10); b = B(20); c = C(30);
>> a + b
called A::plus
ans =
40
>> b + a
called B::plus
ans =
50
>> c + a
called C::plus
ans =
1030
>> a + c %% note
called A::plus
ans =
50
>>
Note "a + c" calls the address@hidden That was unexpected: I suppose that is
what
"InferiorClasses" is all about. Will check that next..., stay tuned.
So far, the results from Octave are the same:
octave:1> a = A(10); b = B(20); c = C(30);
octave:2> a + b
called A::plus
ans = 40
octave:3> b + a
called B::plus
ans = 50
octave:4> c + a
called C::plus
ans = 1030
octave:5> a + c
called A::plus
ans = 50
octave:6>
