Yes, it is possible to generate embedded code with a user-defined order of function arguments for a reusable function in Simulink. Simulink provides several ways to customize the code generation process to meet specific requirements.
One approach is to use the Simulink Coder's customization features, such as the Target Language Compiler (TLC) files and the Embedded MATLAB Function block. TLC files allow you to customize the code generation process by defining templates for generating code from Simulink models. By modifying the TLC file, you can control the order of function arguments in the generated code.
Here are the general steps to achieve this:
- Create a Simulink model and define the reusable function using an Embedded MATLAB Function block. Inside the block, write the code that implements the function logic.
- Open the Configuration Parameters dialog in Simulink and navigate to the "Code Generation" section. In this section, you can specify the TLC file to use for code generation.
- Create or modify the TLC file associated with your model. In the TLC file, you can define templates for generating code from Simulink blocks, including the Embedded MATLAB Function block.
- Locate the template for the Embedded MATLAB Function block in the TLC file. Modify the template to reorder the function arguments as per your requirements.
- Generate code from the Simulink model using the modified TLC file. The generated code will now have the function arguments in the desired order.
By customizing the TLC file, you can achieve flexibility in generating code that matches the order of function arguments required by your external C code.
