Is is possible to use callbacks to call a .m script every second from a Simulink Model?

I have looked into converting it to a matlab function so I can use the sample function however it generates code so am unable to there.

I have also investigated using an initial callback for the code gen part and then using a matlab function for the repetition, however there are lots of parameters I need to pass between the two so that is also seeming like a dead end.

Hi Grace,

It sounds like you're trying to integrate code generation within MATLAB with some iterative or repetitive processing, but you're facing challenges due to the complexity of passing parameters between different parts of your code, especially between the code generation phase and the execution phase within MATLAB functions.

Here are a couple of approaches that might help streamline the process:

1. Simplify parameter passing by encapsulating parameters in structures or classes. This approach reduces the complexity of function interfaces, allowing you to pass a single structured object instead of multiple individual parameters.
2. For integrating codegen for C/C++ code generation from MATLAB code, ensure compatibility by avoiding dynamic typing and unsupported functions. Use structures for passing parameters to the function intended for code generation, facilitating easier management of input parameters.
3. Break your code into smaller, manageable functions or modules, each handling specific tasks. This strategy, combined with using structures or classes for parameter passing, enhances code maintainability and readability.

Hope this helps.
