Hi guys,

I have a program in MATLAB that performs a few tasks.

In the process of solving the problem at hand I had to make a python script that does something and then the data needs to be returned back to MATLAB for machine learning.

I have all the code working fine but I need to run code in MATLAB, then save a CSV file, run a Python script and save in CSV again only to return to MATLAB for getting results.

So all in all I have 2 MATLAB scripts and 1 Python script that I need to combine.

I know that there's ways I could combine the two programs, what's the best way to do it?

If I am able to run this python script in MATLAB, how will I have access to the variables I have there? (for example: my python script returns a pandas dataframe which I save as a csv then run a MATLAB program on)

Hi,

We have some great resources on our GitHub page for calling Python from MATLAB

https://github.com/mathworks/matlab-with-python

This repo shows how you can use a live task to copy and past python code directly into a live MATLAB script:

Hi David.

The resources you call "great" look like "greatly involved and complex". In a word: isn't "speech recognition" a little bit overshot to understand the basics of MATLAB-python interaction?

Anything easier?
