Backtrace would be useful here. It's probably best to recompile with

something could have gone wrong?

Actually, I think you are correct. My bad. I was mainly thinking in

translating back...

minimum value in it. Then, when scanning for the min dist, you only
need to scan O(n) rows.

in the row you're updating if they are the same as the

If the rest of the matrix is already zeros and memory wasn't a
problem, you could just use
A_sym = A + A.T - diag(diag(A))
If memory was an issue, I'd suggest weave.inline (if that's a viable
option) or pyrex to do the loop, which would be about as fast as you
could get.

I would definitely suggest using scipy's weave.inline for this. It
seems like this particular function can be translated into C code
really easily, which would give you a HUGE speed up. Look at some of
the examples in scipy/weave/examples to see how to do this. The numpy
book also has a section
