I'd be very surprised if there was any substantial difference, UNLESS there's
some reason that SPM5 doesn't work properly with matlab 6.5. (But in that
case, there should be an error and it shoudl stop running.)
The _most_ I would expect would be a difference on the order of machine
precision. Anything larger, something funny is going on, or maybe you made a
trivial mistake entering something.
