Specify the behavior of undefined functions in the C source code file of a model that contains C Caller, C Function, MATLAB Function, or MATLAB System block or a Stateflow® chart. If a function is declared in the source header file but not implemented in the source code, Simulink® behaves according to this setting.
Category: Simulation Target
Return error if a function in the C source code is undefined. A stub function is not generated automatically, but function is visible on the C Caller Port Specification table.
Filter out any undefined functions in the C source code. A stub function is not generated automatically, and the function is not visible on the C caller Port Specification table.
If you have any undefined functions in the C source code and they are called in a model that uses a MATLAB Function or MATLAB System block or a Stateflow chart, Simulink returns an error. If the custom code to any of your blocks in your model has undefined functions, Simulink displays a warning.
Do not detect
Do not detect any undefined functions from the source code. A stub function is not generated automatically, but function is visible on the C Caller Port Specification table.
Use interface only
Detect any undefined functions from the C source code. Generate stub functions for the undefined functions and make them visible in the model and callable from Stateflow charts and C Function, MATLAB Function and MATLAB System blocks.
