How do I create a S-Function with generated Code (Simulink Coder)?
显示 更早的评论
I want to generate Code from a Model (e.g. a Subsystem), modify the Code, and create a S-Function with the modified Code. The Code-generation isn't the Problem - i think - I'm just using Simulink Coder to generate the Code. The Problem is to create a S-Function with the generated Code. It doesnt work, even if I dont modify the Code.
What I've tried:
- Creating a .mexw64 file by using "mex" in the Console - that worked so far, but I couldnt connect the mex file with a S-Function.
- Using legacy code Tool - the S-Function I generated with legacy_code doesnt have In/Output ports. The OutputFcnSpec of legacy code would be very much effort to write, if its a complex model.
Is there an easy way to do this?

What I know is that you cann't create a S-function by use the code which generated by Simulink coder. If you want to create a S-function in a simple way, you should follow Madhu Govindarajan's answer.

You can create subsystems out of algorithms that are of concern and right click on the subsystem > C/C++ code > generate S-function, this way you can create the S-function directly without having to create the code and modify it. But if that is part of your workflow then I am not sure how to go about this, maybe there is a way to parameterize stuff in S-functions.

Hi Madhu, What you are saying that, if we follow right click on the subsystem > C/C++ code > generate S-function. Which means we don't need to generate code for S-function correct?
Is this apply for Targetlink block in simulink model?

Thanks Madhu. Neat and simple it worked perfectly.
