Calling Mex File inside a Matlab Engine Call from Python, matlab.eng​ine.Engine​Error: MATLAB function cannot be evaluated, SystemError: MATLAB process cannot be terminated

I have an imaging pipeline that is in Python, this pipelline needs to call a scripts Matlab doing wavelet filtering. However the Matlab code I have is calling some compiled C code. I know it seems completely absurd but for now I have to go this way.

Is it possible to call a C mex file through Matlab called by python with the Matlab engine?

Thanks.

Here is the full error message I get:

hello, do you solve this problem. i have the same problem, can you please help me.

[Arya YAZDAN PANAH]

In my case it so happened that the problem was comming from the mex compilation itself. On my workspace the gcc default version for matlab compatibility was matlab 2017 so switching to this version of matlab solved my issue.

Tharks for your answer。I have slove this problem by sharing this matlab session with python.

I also have this question, can you please tell me how do you share the matlab session with python?
