all() & sparse()

[Jeremy Reynolds]

Hi all,

I'm curious if anyone else has noticed an odd behavior for the all()
function with sparse matrices. Basically, it appears to be broken for small
matrices (which I realize is atypical use for the use of sparse).

For example, just taking the simple case:

all([1 0]) returns 0 as it should, but
all(sparse([1 0])) also returns 1

This doesn't just apply to vectors, but also to matrices:
all([1 0; 1 0; 0 1;]) returns [0 0], and
all([1 0; 1 0; 0 1;],2) returns [0 0 0]', 
but:
all(sparse([1 0; 1 0; 0 1;])) returns [1 0]

(all(sparse([1 0; 1 0; 0 1;]),2) returns the appropriate column vector)

This is with octave 3.2, tested both with the mac OS X binary, as well as a
source install on a kubuntu box.

Am I just missing something, and has anyone else seen this behavior?
