"Simulink Linearization Issue"
显示 更早的评论
"MATLAB 2025a features a more professional user interface and improved computational speed, but it also introduces new error messages. I encountered a linearization failure error in Simulink while working with a jet engine model composed of T-MATS (a NASA-developed turbofan engine modeling toolbox) components. The current error message is as follows: 'Error: STD exception 'class std::bad_function_call': 'bad function call' caught.' It appears to be an issue with the underlying MEX function. How can I resolve this?"

Hi Zhizheng,
Can you provide more details regarding the issue:
- When is does the error occur: while updating the model or when running the model?
- Is the same error observed when working on any other example or blocks from T-MATS repo? Which model or block is causing this error?
- You mentioned observing this error in MATLAB R2025a. Did the same model work in any previous MATLAB versions? If yes, please specify which version.
