I'm a bit embarrassed to ask this, but here goes:
If I let a=[1,2;3,4]; and then ask for sum(a), sum(a,1) and sum(a,2), I
get the answers
4 6 4 6 3
7
respectively. Now I let a=[1,2]; and do the same. I now get
3 1 2 3
indicating that in the second case sum(a) != sum(a,1), in direct violation
of the documentation in the manual. Is this supposed to be like this and
didn't I understand things, or is it a bug? (Octave is 2.1.57.)
Kind regards,
Maarten
