Could someone run the following in Matlab and report the results? There
may be errors, but that would be interesting.
x = javaObject ('java.lang.String', 'Hello');
ischar (x)
y = [x ' World']
class (y)
z = javaObject ('java.lang.Double', 4.2);
isnumeric (z)
t = z + 3.1
class (t)
w = single (z)
w = uint8 (z)

>> x = javaObject ('java.lang.String', 'Hello');

ans =
0

??? Error using ==> horzcat
The following error occurred converting from char to opaque:
Error using ==> horzcat
Undefined function or method 'opaque' for input arguments of type 'char'.
>> class (y)
??? Undefined function or variable 'y'.

??? Error using ==> single
Conversion to single from java.lang.Double is not possible.
>> w = uint8 (z)
??? Error using ==> uint8
Conversion to uint8 from java.lang.Double is not possible.
