Matlab is also just a Python package
{:.no_toc}
* TOC {:toc}The goal
Remote controlling Matlab from Python using the Matlab engine package. (Note: A similar approach can be used with C/C++ instead of Python.)
Questions to David Rotermund
Installing Matlab under Python
Versions of Python Compatible with MATLAB Products by Release
Obviously you need a working Matlab and Python installation first. Then...
Linux
Open a terminal and do this (please adapt to your Matlab and Python version / installation path). And make sure that you use the correct Python installation for this operation, otherwise you will be confused why it will not work.
cd /tools/matlab2023b/extern/engines/python/
/data_1/davrot/P3.11/bin/python3 ./setup.py install
You get something like this as a response:
running install
running bdist_egg
running egg_info

Windows
Open a Power Shell as administrator under Windows and do this:
cd "C:\Program Files\MATLAB\R2023b\extern\engines\python"
python.exe .\setup.py install
Start the engine
Under Python we now can connect to Matlab:
import matlab.engine
eng = matlab.engine.start_matlab()
