 Matlab allows a second parameter in SUM(X,D)
 That would be nice in Octave, too.

 SUM Sum of elements.
 For vectors, SUM(X) is the sum of the elements of X. For
 matrices, SUM(X) is a row vector with the sum over each
 column. For ND arrays, SUM(X) operates along the first
 nonsingleton dimension.

 SUM(X,DIM) sums along the dimension DIM.

 Example: If X = [0 1 2
 3 4 5]

 then sum(X,1) is [3 5 7] and sum(X,2) is [ 3
 12];
This feature is already on my (long) list of projects. Would anyone
be interested in contributing code? If so, please contact me first as
I have some ideas about how it should be done.
Thanks,
