Specify the behavior of undefined functions in the C source code file of a model that contains C Caller, MATLAB Function, 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
Default:
Filter out
Throw
ErrorReturn 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 outFilter 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, 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
detectDo 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
onlyDetect any undefined functions from the C source code. Generate stub functions for the undefined functions and make them visible in the model and to call from Stateflow charts, C Function, MATLAB Function and MATLAB System blocks.
