Eh ... swapping two columns filled with zeros has no net effect, or does it?

@Jos — As is the case with a lot of Questions here, I suspect this is a proxy for a different problem.

well you can achieve this by
test = randi(10,2,10)
hfliptest = test(:,end:-1:1)
i cant remember if there is a built in function to do this. perhaps someone else knows but this should do it.
**edit oh there it is fliplr.
