run python script in parallel to matlab

Question

I have 2 scripts:

python script
matlab script

I need to run this two scripts in parallel (no output for both of them). I was thinknig to call to the python scirpt, from the matlab script.

I know it is possible to run python script from matlab like:

systemCommand='my_script.py'
system(systemCommand)

however in this way, the matlab script will wait to the return of the python script, and the rest of my matlab script will not be executed.

any ideas?

Have you tried appending an ampersand (&) to the end of your system command to send it to the background? ('my_script.py &') — Suever

I have gone ahead and added it as a format answer. Glad it worked for you. — Suever

As mentioned near the end of MATLAB's system documentation in the "Tips" section, to run a system command in the background (on *nix), you can append an ampersand(&) to the end of your command to tell it to run in the background.

system('my_script.py &')

If you're on Windows, you'll want to use the following to prevent a command window from opening.

system('start /b my_script.py');

Do you know how can I close the cmd that opens for the python script after I have finished using it?

At the end of your python script, do you have sys.exit(0)?
