Here 's' is a 'double' and 'z' is 'uint8'. In matlab, when you concat a
double and an uint8 you get an uint8. In Matlab 7.6 I see:

        >> class ([uint8(1), double(1)])
        
        ans =
        
        uint8

So, this behaviour is compatible. My guess is that people mostly use the
integer classes to save memory, so Matlab downgrades other types to
integers when in doubt, to make sure that memory usage doesn't blow up.
