Hi Zewen,
I see that you are facing the error ''Unrecognized function or variable 'main' ". The error message "Unrecognized function or variable 'main'" typically occurs when MATLAB Coder cannot find a function named 'main' that you are trying to use in your code.
This can happen for a few reasons, especially if you're coming from a programming background where main is a conventional entry point for programs (such as in C or C++). In MATLAB, the entry point for a program can be any function, and the name main is not special unless you have defined it yourself.
You can solve this issue by making sure of the following points:
- Ensure that you have a function named 'main' defined in a file named 'main.m'.
- Ensure that the file containing the main function is in the current folder or in MATLAB's search path. You can add a folder to MATLAB's search path using the "addpath" function.
- Make sure you are specifying "main" as the entry-point function if that's your intention, and ensure that it matches the name of the function you intend to use. This can be done programatically or using the GUI.
- If you're using MATLAB Coder through commands, ensure you specify main correctly in your 'codegen' command. A sample command would look like :
codegen -config:mex main -args {input_example}
Hope this helps!
