Hi,

I understand that MATLAB is crashing when you use your custom MEX file. This often happens when there is memory corruption in the MEX function, such as accessing non-existent input or output arguments, improper memory allocation, or incorrect array indexing. Please double-check your code for these issues, ensuring you always check the number of input/output arguments.

To help you debug the MEX file, you can use the following documentation:

https://www.mathworks.com/help/coder/ug/running-debugging-mex-functions.html

To use tools like Microsoft Visual Studio for debugging follow the mentioned steps in the below answer by MathWorks staff:

https://www.mathworks.com/matlabcentral/answers/99464-how-do-i-debug-a-matlab-7-4-r2007a-c-c-mex-file-in-intel-visual-c-9-1-using-microsoft-visual-s

Hope this helps!

Thank you for your reply. I also wondered if it was a problem of missing input parameters. The more detailed situation I have is that by importing other IP cores from Vivado (such as FIFO and FFT), setting the initial values, and not configuring the inputs in Simulink, everything can run normally. The LDPC IP core has also correctly set the initial input in the Verilog file of Vivado (imported by CosimWizard), and the correct waveform diagram is displayed. This operation is the same as that of other IP cores. However, only the LDPC IP core caused a crash when imported into Matlab.
