This is a case of bug-for-bug compatibility.

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

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.)
