Define Inline function for specific subsystem in generated auto code by embedded code in Simulink

Is it possible to define a inline function in autocode for secific subsystem

Inline void func()
{
}
void model_step()
{
func();
}

I have checked this documention --> https://in.mathworks.com/help/simulink/slref/subsystem.html . But Its not explaining that

Hi Jarvis,

Yes, it is possible to control how code is generated for a specific subsystem in Simulink using Embedded Coder. By default:

• Virtual subsystems do not generate a separate function in the code; their contents are inlined directly into the parent function.
• Atomic (nonvirtual) subsystems typically generate a separate function for the subsystem. However, you can configure how this function is generated, and it can be configured to be inlined as well.

To explicitly define an inline function for a specific subsystem:

1. Right-click the Subsystem block and select Block Parameters (Subsystem).
2. In the dialog box, ensure "Treat as atomic unit" is checked. This makes the subsystem atomic (nonvirtual) and allows for advanced code generation options.
3. Go to the Code Generation tab.
4. Set the Function packaging parameter to Inline.

The documentation for the same can be refered to at: https://www.mathworks.com/help/rtw/ug/inline-subsystem-code-ecoder.html

Actually I have tried that option also. But problem even though If you select function packaging as inline the code is inline in actual function in generated code Its not generating like inline custom_func() { } void step() { custom_func(); }

[jarvis]

yes. MATLAB is not generating code like inline function.

I don't know wheather that feauture is available or not
