I’m fairly sure this can be avoided completely because you run your Julia code in a separate operating system process. I haven’t used matlab for a long time, but IIRC the problem here is because matlab likes to set environment variables `LD_LIBRARY_PATH` (and possibly `LD_PRELOAD`?) which breaks the invocation of user executables with matlab’s [`system`](https://www.mathworks.com/help/matlab/ref/system.html) function (sigh… matlab 🤦‍♂️)

This problem is described here: [Why does Matlab set a custom LD\_LIBRARY\_PATH when execting "system" on Linux? - MATLAB Answers - MATLAB Central](https://www.mathworks.com/matlabcentral/answers/181899-why-does-matlab-set-a-custom-ld_library_path-when-execting-system-on-linux)

The solution is to unset the necessary environment variables, or otherwise undo whatever crimes matlab has committed against your OS environment.
