Include headers

R2026b

Include custom code in the generated model header file

Model Configuration Pane: Code Generation / Custom Code

Description

Specify custom code to include near the top of the generated model header file.

Settings

'' (default) | string

The code generator places this code near the top of the generated model.h header file. If you are including a header file, in your custom header file add #ifndef code. This avoids linker errors and multiple inclusions. For example, in rtwtypes.h the following #include guards are added:

#ifndef RTW_HEADER_rtwtypes_h_
#define RTW_HEADER_rtwtypes_h_
...
#endif /* RTW_HEADER_rtwtypes_h_ */

Tips

To use the same custom code settings as those used for simulation, select Use the same custom code settings as Simulation Target. For more information, see Integrate External Code by Using Model Configuration Parameters.
