Hi @Mohammed Afandi,
To modify the generated C++ code so that parameters are passed to the "Model_step" function as a structured type using Simulink and Embedded Coder, follow these steps:
Part 1: Environment Setup
- Open your Simulink model.
- In the Apps gallery, select "Embedded Coder".
- On the "C++" Code tab, choose "Embedded Code - C++".
Part 2: Configure Code Mappings
- Go to "Code Interface > Code Mappings".
- In the "Functions" tab, find "model_step".
- Click the hyperlink in "Function Preview" to edit the function signature.
- Define a "param_type" struct with your parameters and set it as the input argument for "model_step".
You may also refer the below documentation to Configure Parameters for C++ Interface Code Generation: https://www.mathworks.com/help/ecoder/ug/configure-parameters-for-c-code-generation.html
Part 3: Define Parameter Structure
- Create a header file (model.h) and define the struct:
typedef struct {
real_T param1;
real_T param2;
} param_type;
- Ensure "model.h" is included in relevant files.
Part 4: Generate and Verify Code
- Click "Generate Code" in the Embedded Coder app.
- Check "model.cpp" to confirm "Model_step" uses "param_type":
void Model_step(param_type params) {
// Use params.param1 and params.param2
}
This approach ensures parameters are passed as a structured type, enhancing code clarity and organization.

I hope this helps!
