How to implement Macro function in simulink.

Hi All,

How can we implement Macro function in simulink.

 ex:  #define MAX(a,b)                (((a)>(b))?(a):(b))

Note: Matlab version: 2018a, Embedded coder for code generation. Regards, sai

You might define a custom header file on the "Simulation Target" tab of your model's parameters. Place a respective file in the directory of that model. I haven't tried with macros yet, but if you declare a function in that header and also provide a custom source file implementing that function, you'll be able to use it in your C-type Stateflow chart. Don't forget to place the same settings at "Code Generation" -> "Custom Code" if you intend to generate code from that model.
