Integrate C/C++ Code into Simulink - MATLAB & Simulink (original) (raw)

Main Content

Integrate existing C/C++ Code into Simulink®

Choose the appropriate C/C++ code integration tool for your model:

• If you have simple C/C++ functions that you want to integrate and its Simulink implementation does not require advanced block customizations, use C/C++ code importers.
• If you have C/C++ code that you want to integrate, use the C MEX S-function when its Simulink implementation requires:
  • Continuous or discrete states
  • Multirate ports
  • Variable sized input and output ports
  • Zero-crossing detection
  • Complete interaction with Simulink engine
    This workflow might require manually creating a Target Language Compiler (TLC) file for code generation.
• If you have simple C/C++ code that you want to integrate and want to generate code without manually writing a TLC file, use S-Function Builder.
