[Octave-bug-tracker] [bug #51333] Reductions on an empty matrix is inconsistent

[Sarrah Bastawala]

Follow-up Comment #8, bug #51333 (project octave):

I have understood the mistake in my understanding, and by changing the code
after the reduction has taken place for the special case of an empty matrix, I
was able to procure these results :
 

octave:1> dot([],[])
ans = [](0x0)
octave:2> dot([],[],1)
ans = [](1x0)
octave:3> dot([],[],2)
ans = [](0x1)


which are completely compatible with what Matlab does. I have added some tests
to check for empty inputs, and my changeset passes all pre-existing and new
tests. Please have a look!
