Can Matlab System Object class inherit from a "regular" class? Anyone has an example?

I am trying to get a Matlab System Object class that I use in Simulink to inherit from another class apart from the fact that it has to inherit from matlab.System. However, once I add the that class as follows:
classdef siggen < matlab.System & classA
I automatically see this error in Simulink:
Invalid setting in '.../Subsystem/MATLAB System' for parameter 'System'. Caused by:
Error evaluating parameter 'System' in '.../Subsystem/MATLAB System' Caused by:
Not enough input arguments.

Hi Ibra,
You should be able to inherit from a different class. I am attaching a small example here to demonstrate this.
Are you able to use this class in MATLAB and not just in Simulink? For example, can you use the following commands?
myObj = siggen;
"args" refer to the arguments in your siggen step function, usually specified as the stepImpl function in MATLAB System class.
