How to run a m-file in OPAL-RT?

How can we run a script (MATLAB program) file that needs to run real time using OPAL-RT software and hardware?

Hello Yugeswar,

Have you got the Answer? I also want to know, "whether can we run only MATLAB script (m) file in OPAL-RT?

Please let me know.

Thank You.

Hi Yugeswar,

I also was looking for this, but could not find any resources that suggest we can call M file in OPAL-RT. I worked around it by using Python as an intermediary. That is, by calling the M file in Python and integrating Python with OPAL-RT.

MATLAB functions may be called from python using MATLAB Engine API for Python. Detailed instructions can be found in the following documentation:

• https://www.mathworks.com/help/matlab/matlab_external/call-matlab-functions-from-python.html

Once the MATLAB script is accessible in Python, it can be integrated with OPAL-RT. The following resources provide guidance on using Python with OPAL-RT:

• Test Automation using the Python API: https://www.opal-rt.com/opal_tutorial/more-tutorials-2-test-automation-using-the-python-api/
• Using Python Script: https://opal-rt.atlassian.net/wiki/spaces/PRD/pages/143691049/Using+Python+Script
