kbhit oesn't seem to work in Matlab 2017b. I get this error message:
Error using set
The name 'Userdata' is not an accessible property for an instance of class
'com.mathworks.mde.cmdwin.CmdWin'.
That occurs in the init, i.e. kbhit('init') in:
set(KBHIT_h_cw, 'userdata', []);
I don't see a property method/accessor for "userdata"

Replace your kbhit.m with the one attached here, it should work. The original version tried to store key event data in the 'Userdata' property of the command window object, however it is no longer viable in later Matlab versions. What I did was just to asign key event data directly to a global variable.

for MATLAB:
while true
ch = getkey
if ch != 165 break; end
end
----------------------
for OCTAVE
while true
if kbhit(1) break; end
end
-----------------------------
while true
% 165 ASCII code for null
if kbhit(1) != 165 break end
end
--------------------------------------
