MATLAB: How to customize the code interface of a function generated of a reference model

code generationEmbedded Codersimulink coder

I was working on a code-generation project with a top model and several referenced models. I found it very easy to customize the name and argument of any entry-point functions in top model after following the link:
However, I could not find where to customize the function interfaces for referenced models. One of the referenced model I have takes a single input and return a single output, and the generated code has the function like:
void foo(const real_T *input, real_T *output);
I want it to be configured as:
real_T foo(const real_T input);
Could anyone give me some guidance?
Much appreciated!

Dear Boru,
If you have Embedded Coder, it is possible to control the entry points using the Function Prototype Control feature (https://www.mathworks.com/help/ecoder/ug/function-prototype-control.html). Basically, you can specify a new name for the "step" function, and each of the root-level ports become function arguments or return values. You can also specify smaller details about these arguments, such as adding "const" or making them pass-by-value or pass-by-reference.
