I am using Matlab embedded coder but when I want to generate code that shows " too many input arguments " error at the end of code producing process

thanks

Hi Esmaeil,

There could be multiple possibilities here, can you share build log?

Hi,

The error "too many input arguments" during code generation with MATLAB Embedded Coder often does not clearly indicate the underlying issue. If you are encountering this problem, it might be due to a configuration or installation error. Here are some recommended steps to troubleshoot:

1. Regenerate MATLAB Preferences: Sometimes, resetting MATLAB preferences can resolve unexplained issues. You can do this by renaming or deleting the preferences directory.
2. Upgrade Advisor: If you are transitioning between different MATLAB versions, use the ‘Upgrade Advisor’ to ensure compatibility and resolve potential issues. For more information on the ‘Upgrade Advisor’ you may refer to this documentation: https://www.mathworks.com/help/simulink/slref/upgradeadvisor.html.
3. Simplify Directory Path: Move your model to a simple and short directory path, such as the Desktop. Windows can be particular about file paths and simplifying them can sometimes resolve issues.
4. Check for Function Name Conflicts: Refer to this existing MATLAB answer where a similar issue was resolved: https://www.mathworks.com/matlabcentral/answers/621508-too-many-i-ps. The error occurred because the user created a function with the same name as an inbuilt function. Ensure your custom functions do not share names with MATLAB's inbuilt functions.

Additionally, it is beneficial to gather information about your compiler for code generation. To do this in Simulink, navigate to ‘Settings’ > ‘Code Generation’ and check the value listed under the ‘Toolchain’ option.

Hope this helps !
