Execution of script BuildExpertSystem as a function is not supported

In the process of running a function and their parallel scripts issues are displayed, the three files are as follows:

ExpertSystemDemo.m

your BuildExpertSystem is a script that builds a 3 x 2 cell array and then throws it away. But you are invoking it as a function with a whole bunch of arguments, expecting it to return something. These uses conflict.
