Matlab 2023a python engine fails to start

I've installed the python engine for Matlab2023a using the methods described in the documentation here

The installation messages claims success but, when I try to load the engine on a python terminal i get the following error:

Python 3.10.13 (main, Sep 11 2023, 13:44:35) [GCC 11.2.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import matlab.engine

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "/software/anaconda/2019.03/envs/gsilva/lib/python3.10/site-packages/matlab/__init__.py", line 218, in <module>

from matlabmultidimarrayforpython import double, single, uint8, int8, uint16, \

ImportError: /software/matlab/R2023a/extern/engines/python/../../../extern/bin/glnxa64/../../../sys/os/glnxa64/libstdc++.so.6: undefined symbol: __cxa_thread_atexit_impl

What should I do?

Hi Gustavo Silva,

I understand that you are trying to run the ‘MATLAB engine’ directly from the Python terminal, but this is not possible. To use 'MATLAB engine' in Python, you need to create a Python script. Inside the script, you can import and start the 'MATLAB engine' using the following commands:

import matlab.engine 
eng = matlab.engine.start_matlab() 

You can execute the python script, by calling it from MATLAB using the 'pyrunfile' function.

For more information regarding 'pyrunfile', please refer to the following documentation: -

I hope this helps!
