Details:

Here is a small demo code to show what I mean:


vec = uint8(1) : uint8(5)
class(vec)


In Matlab the result is 'uint8', but in current Octave I get the result
'double'. (The behavior for uint16 and int16 is the same as for uint8 in
Octave.)

The current Octave result is very unexpected to me (in fact it took me several
years to figure this out in bug #55059) and it is incompatible to Matlab.
