MATLAB: Non inlined S function in a protected model

protected model; non-inlined s functionsimulink

I have a non-inlined S-function in a MDL. I need to create a protected model of this MDL. I am not very experienced with converting a non-inlined S function to an inlined S function. What are my options here to create the Protected model which contains a non-inlined S function inside the MDL.

Thanks

According to the documentation:

A protected model cannot use noninlined S-functions directly or indirectly.

So unfortunately, it looks like you must write a TLC to make it an inlined S-function.

http://www.mathworks.com/help/techdoc/matlab_oop/brqy3km-14.html#brqy3km-15 under "Specify Method Attributes in classdef File" ...

Basically, inside the class definition create a methods block with properties Acess = protected. Inside that block add the function footprint.

methods (Access = protected)
  [a,b,c]=protectedmethod(x,y,z);
end

Then create a seperate m file in the root class directory named protectedmethod with the header

function [d,e,f]=protectedmethod(u,v,w)

Hi Kidus,

Generating code for a model that has an S-function does require you to provide a TLC file. When a model is built, it assumes the generated code will be used in a MATLAB-free environment. Under that assumption, the coder needs to know how it can inline the code of your S-function in the generated C code. An S-function TLC file tells the coder how to do this.

There are many resources within the MATLAB documentation that can guide you on how to write TLC files for S-functions. I would recommend starting with this documentation page to learn more about inlining S-functions: https://www.mathworks.com/help/releases/R2017a/rtw/tlc/inlining-s-functions.html.

Another documentation page that would be helpful is this tutorial on creating TLC files for S-function blocks and generating code. https://www.mathworks.com/help/rtw/tlc/inlining-s-functions-with-tlc.html
