Settings

Default: C

C

Compiles custom code using rules of C.

C++

Compiles custom code using rules of C++.

Select the C++ option to:

  • Generate MATLAB Function block or Stateflow chart MEX code as C++ files and compile custom code using C++. For MATLAB Function and MATLAB System blocks, if you add C++ code to buildInfo using coder.updateBuildInfo or coder.ExternalDependency, set Language to C++.

  • Simulate a MATLAB System block through code generation and compilation using C++.

Before you build a system, configure Simulink to use a compiler system using mex -setup.
