To prepare SimBiology® models for accelerated simulations, install and set up a compiler:
Install a C compiler (if one is not already installed on your system). For a current list of supported compilers, see Supported and Compatible Compilers.
Ensure that any user-defined functions in your model can be used for code generation from MATLAB®, so they can convert to compiled C. For more information, see Language, Function, and Object support for C and C++ code generation (MATLAB Coder) or contact MathWorks Technical Support.
On Windows®, if you have not installed another compiler, SimBiology uses the lcc-win64 compiler for model accelerations. If you have installed another supported compiler, it will be selected automatically. For better performance of the acceleration functionality, you may want to install a supported compiler other than lcc-win64, and it will be selected automatically.
