Does Simulink Real-Time support MATLAB-S Functions?

The Help Documentation seems to say Simulink Real-Time support C-S Functions. So does Simulink Real-Time support MATLAB-S Functions?

Yes. See for example https://www.mathworks.com/help/xpc/driver/s-function-guidelines.html that talks specifically about writing drivers for Simulink Real-Time using S functions. (Note: the S functions cannot be written in MATLAB.)

You are right, Paul.

Hmmm... related:

https://www.mathworks.com/help/slrealtime/advanced-modeling-techniques.html

https://www.researchgate.net/post/Why_we_cannot_use_S-function_for_real-time_applications

But it does look as if the direct documentation on this topic might have been removed, with it perhaps being assumed that anything like this would be done in Speedgoat.

If you'd like to know more about how to integrate and deploy S-Functions to a Simulink Real-Time target, or in general, any external C/C++ code, please check out the following documentation page.
