To model your design, you can integrate external software with your real-time application. You can access external software with Simulink® S-Function blocks written in C or in Fortran. Using Fortran requires processing steps beyond the steps required to write an S-function in C.
Implement Algorithms Using MATLAB (Simulink)
Implement a new algorithm using MATLAB®
Implement Algorithms Using C/C++ Code (Simulink)
Implement a new algorithm using C/C++ code
Implement Algorithms Using Fortran Code (Simulink)
Implement Fortran code in custom Simulink blocks
Implement Algorithms Using Legacy Code Tool (Simulink)
Integrate existing C or C++ functions, such as device drivers or external simulation code
S-Functions (Simulink Coder)
Develop S-function to represent external code and inline S-function with Target Language Compiler (TLC) block target file
Use Simulink S-functions to incorporate Fortran code into a real-time application.
