I feel like i am almost there but need the extra push! I am trying to call a MATLAB script from Python (I'm not worried about the output of the MATLAB script - it runs independently). However, i must be able to send an input into the MATLAB script from python.

Right now I have(in python):

myvartoinput = 55
cmd = 'myscript.m'
process = Popen(["matlab", "-nosplash", "-nodesktop", "-r",  cmd], shell=True)  
process.communicate()

# Also, how do i 'exit' the MATLAB so it doesn't continue to run

I am not sure how to add "myvartoinput" into the 'myscript.m' file. Also, did I call the script correctly? Finally, i would like it to "exit" so it doesn't stay open in the background on my pc. Any help would be appreciated!

I have solved it differently:

import os 
import subprocess
myvartoinput = 55

subprocess.call(['matlab', '-wait','-nosplash','-nodesktop','-r','myscript(\'%s\')' %(myvartoinput )])

Arguments:

'-wait' - python waits till Matlab executes script and continues;

'-nodesktop' - only matlab command window is called;

'-nosplash' - suppresses the display of the splash screen;

'-r' - argument after which follows name of a script
