Dear Rik ,
It seems there are some paranthesis missing, I guess you meant
...uint8([2 3;4 5])...
I checked R2018a, R2016b, R2013a, and the results are:
----------------
>> version
ans =
'9.4.0.813654 (R2018a)'
>> x = kron(uint8([2 3;4 5]), ones(2,2,'uint8'));
>> class (x)
ans =
'uint8'
>> y = kron(uint8([2 3;4 5]), ones(2,2,'int16'))
