Oops, I was in a hurry and should have checked the code more carefully. 
But yes, that was what I intended.  It seems like kron does preserve the
class of the input in the output.  If that is the case then mixed floating
point, integer cases probably result in an integer output.  Could you try
this last test?

x = kron (uint8 ([2 3;4 5]), ones(2,2));
class (x)

I suspect it will be uint8 rather than double.
