Language

Specify C or C++ code generation for simulation targets. This configuration parameter affects:

Model reference simulation targets.
Rapid accelerator simulation targets.
Custom code you implement with C Function blocks, C Caller blocks, MATLAB Function blocks, MATLAB System blocks, and Stateflow^® charts. If Import custom code is selected, available custom code variables and functions are parsed.

The Simulation cache folder configuration parameter determines where to save the generated C or C++ files.

Category: Simulation Target

Default: C

C

Generates C code for simulation targets.

C++

Generates C++ code for simulation targets.

Select the C++ option to:

Generate MATLAB Function block or Stateflow chart MEX code as C++ files and compile 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++.
Use a C Function block to interface with C++ classes defined in your custom code. See Interface with C++ Classes Using C Function Block.

A model cannot have a C++ simulation target if it contains a Simscape™ block with a source file that contains MATLAB^® functions.

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

Parameter: SimTargetLang
