Deal with Closed MATLAB Executable and Windows command line

I was provided a closed matlab code (exe) built by matlab application. When I ran it, I see that there are some UI with some input parameters and some output parameters. I'd like to send some inputs from windows command line and get the output.

I've tried to do so by

my_app_name input1 input2 ...

, but i'm getting an error like: The input to str2func "input1" is not valid funciton name.

I guess that the function which shall be called is func2 with those input parameters.

How can I do this?

No documentation on how to run the app? Contact the developer.

I wish I had. He refuses to do so

Well, input1 and input2 should be existing functions. If you want to use the functions that are within the executable, then you should know their names.

I don't know much about what could you do, other than waste your time by trying to figure out what is inside the program.

This what I am going to write may not help, but try supplying this as an input, maybe it'll lead you somewhere.

eval("whos")

Based on the error message, it seems that "input1" is passed to the app when you run it in command line

my_app_name input1 input2 ...

which is really good. It indicates that the app is designed to run interactively as well as through API.

What happens if you run str2func('input1') in MATLAB Command Window? Did you provide a valid 'input1', such as

str2func('abs')

ans = function_handle with value:
    @abs
