Programmatically add callbacks to MATLAB system block

I am programmaitcally creating .m files that define a MATLAB system block. I have also created code to execute in the OpenFcn callback. Is there a way to add this code directly in the .m file (e.g. as a method of the system) instead of manually clicking through the GUI and adding the code to the OpenFcn callback?

Thanks!

Yes, you can add code directly to the .m file of a MATLAB system block instead of manually adding it through the GUI. The MATLAB system block is implemented as a MATLAB class, and you can define additional methods and properties in the class file.

Here's an example of how you can add code to the .m file of a MATLAB system block:

1. Open the .m file of your MATLAB system block in a text editor.
2. Locate the class definition of the system block. It should look something like this:

classdef MySystemBlock < matlab.System

% Class definition goes here

% ...

end

1. Inside the class definition, you can define additional methods. For example, let's say you want to add code to the setupImpl method, which is called when the system block is initialized. You can add the following code:

methods

function setupImpl(obj)

% Your code here

% ...

end

end

1. Similarly, you can define other methods such as stepImpl for the main algorithm of the system block, or releaseImpl for releasing any resources when the system block is destroyed.
2. Save the .m file with your changes.

Thanks for your reply. Specifically, I was looking for the right method name add code to the OpenFcn callback. Is that possible?
