Call a simulink function from an s-function

How can I call a simulink function from within an own s-function block?

(There are examples of how to output a function call triggering a function call subsystem. But that's not intended.)

Basically I want to rebuild the existing "Function Caller" block with an own s-function. How does s-function code look like for such an approach?

And will it be linked/ shown by function connectors if simulink function is provided?

Thanks.

It is indeed possible to call a Simulink function from an S-function. For a comprehensive understanding of the various methods to call a Simulink function, please refer to the following MathWorks documentation:

https://www.mathworks.com/help/simulink/ug/simulink-functions-overview.html#mw_c7cc96ae-c60d-4d51-b259-0c85c4560d25

To learn about declaring a call from an S-function, you can consult the documentation on 'ssDeclareFunctionCaller':

https://www.mathworks.com/help/simulink/sfg/ssdeclarefunctioncaller.html?s_tid=doc_ta

For information on making the actual call at runtime using 'ssCallSimulinkFunction' (which should be implemented in either the mdlUpdate or mdlOutput methods), please see the following resource:
