How to write append a few lines in model_initialize function for a MATLAB function block in Simulink?

I am creating a MATLAB function block in Simulink. For that function block I want to append a few lines of code in the model_initialize function. I know that I can just create an initialize subsystem to write that code. However, I do not want to create a separate initialize block.

Is it possible to generate a few lines of code in the model_initialize function for a MATLAB block in Simulink? This is for Embedded Coder code generation.

To insert custom code into the model_initialize function for a MATLAB Function block in Simulink without creating a separate initialization subsystem, you can use the following approach with Embedded Coder:Use Embedded Coder Custom Code Settings

1. Open Model Configuration: Go to Modeling > Model Settings.
2. Navigate to Custom Code: Select Code Generation > Custom Code.
3. Insert Code: Click on the 'Additional Source Code' tab. In the 'Initialize Code' field, enter the custom code you want to include in the model_initialize function.

This method allows you to directly specify initialization code that gets included in the generated model_initialize function without needing to modify TLC files or add additional blocks to your model.
