How to initialize the workspace for a simulink model from a python script using the matlab engine

Hi everyone! I've connected a python script to a simulink model as explained in this tutorial https://medium.com/@soutrikbandyopadhyay/controlling-a-simulink-model-by-a-python-controller-2b67bde744ee. What I would like to know now is: my simulink model calls some variables from the workspace, so is there a way to initialize the workspace using the matlab engine in python?

Hi Francesco,

To initialize the MATLAB workspace using matlab engine you could follow these steps:

1. Share an engine from MATLAB.

 matlab.engine.shareEngine('engine_1') 

2. Connect the shared engine from MATLAB with python program.

import matlab.engine
eng = matlab.engine.connect_matlab('engine_1')

3. Create a python variable and initialize it to MATLAB workspace using the following command.

px = eng.linspace(0.0,6.28,1000)
eng.workspace['mx'] = px

You could find documentation for the same using this command in your MATLAB command window.

I hope this helps with your task!!
