The analoginput function was removed in R2016a. See the release notes here (under Legacy Interface Removed).
Pre R2016a you might do this:
% Legacy code
ai = analoginput('nidaq','Dev1');
addchannel(ai,0);
start(ai);
data = getdata(ai);
Equivalent code starting in R2016a
s = daq.createSession('ni');
addAnalogInputChannel(s,'Dev1',1,'voltage')'
data = startForeground(s);

I'm not sure what it refers to. My searching suggests it is not a property of session-based interfaces. I can't find any references to it at least.

In fact, in general all M-files (Simulink .slx and .mdl files) are forward compatible. However, there a few fcn/command syntaxes have been changed in later versions of matlab. E.g.:
legend('Abc', 'Dce', 1) % Old version
legend('Abc', 'Dce', 'location', 'northeast')

HWInfo = daqhwinfo(analoginput(handles.DeviceName,handles.DeviceID))
the above line has functions that were used in 2015b , can you help me to make it work on 2018b?
