Implement Algorithms Using Legacy Code Tool

Integrate existing C or C++ functions, such as device drivers or external simulation code

You can integrate existing C (or C++) functions, such as device drivers, lookup tables, and general functions and interfaces, into Simulink®模型使用遗留代码工具。使用遗留代码工具指定编译所需的S函数，文件和路径的名称以及所生成的S函数的选项。

Use thelegacy_codefunction to generate an S-function, compile and link the generated S-function, and create a mask for calling the generated S-function.

Before you can uselegacy_code, ensure that a C compiler is set up for your MATLAB®installation.
