Here are a few potential reasons why it's not working:
- The function is not in the MATLAB path: If MATLAB can't find the function definition, it won't open anything. Make sure that the function file is in the current directory or in the MATLAB path.
- The function is built-in or private: Some MATLAB functions are built-in and do not have accessible source code. Similarly, if the function is private to another function or class, you may not have access to open it directly.
- File permissions: If the file is in the path but cannot be opened, there could be an issue with file permissions. Ensure you have the correct permissions to access the file.
- IDE issue: There could be a temporary glitch in MATLAB's IDE. Restarting MATLAB can sometimes resolve these issues.
- Compatibility or bug: If this is a consistent problem and not just a one-time glitch, it might be a compatibility issue with your version of MATLAB or a bug.
- External function: If you can open external functions successfully, it implies that the issue is specific to your app's functions. Ensure that the function definition is not in a private folder and is correctly named.
If the issue persists, you might want to contact MathWorks support for assistance or check the MATLAB Central community for similar issues and potential solutions.
