By setting the model configuration parameter Code interface packaging to
C++ class, you can generate a C++ class interface to model
code. The generated interface encapsulates required model data into C++ class attributes and
model entry-point functions into C++ class methods. The benefits of C++ class encapsulation
include:
Greater control over access to model data
Ability to multiply instantiate model classes
Easier integration of model code into C++ programming environments
C++ class encapsulation also works for right-click builds of nonvirtual subsystems. (For information on requirements that apply, see Configure C++ Class Interfaces for Nonvirtual Subsystems.)
To generate C++ class interfaces in model code:
Configure your model to use an ERT-based system target file provided by MathWorks®.
In the Configuration Parameters dialog box, set Language to
C++.
Optionally, configure related C++ class interface settings for your model code, using a graphical user interface (GUI) or application programming interface (API).
Generate model code and examine the results.
