Executing a python program in a raspberry pi

I am trying to execute a python progam that is located in a folder on a raspberry pi using a Matlab script. You execute this file in the pi using the command "sudo ./". I have attempted to do this using the following command: system(mypi,"/home/pi/Downloads/LeptonModulemaster/software/Raspberrypi_capture/Raspberrypi_capture","sudo").

Please advise.

Thanks

Hi,

According to my understanding you want to run a python file in the raspberry pi to be executed from MATLAB. After the support package is installed and a connection has been creating between raspberry pi and MATLAB.

After creating a connection you can use system function as instructed in documentation.

To execute a python program you use "python filename.py" or "python3 filename.py". Try the following line of code

system(mypi,'python /home/pi/Downloads/LeptonModulemaster/software/Raspberrypi_capture/Raspberrypi_capture.py','sudo');

For more information have a look at this link.

Thanks for the quick response.

I made the appropriate change, but, got the following:

>> system(mypi,'python /home/pi/Downloads/LeptonModule-master/software/raspberrypi_capture/raspberrypi_capture','sudo')

Error executing command "sudo python

/home/pi/Downloads/LeptonModule-master/software/raspberrypi_capture/raspberrypi_capture". Details:

STDERR: File

"/home/pi/Downloads/LeptonModule-master/software/raspberrypi_capture/raspberrypi_capture", line 1

SyntaxError: Non-ASCII character '\x8b' in file

/home/pi/Downloads/LeptonModule-master/software/raspberrypi_capture/raspberrypi_capture on line 2, but

no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

STDOUT:

So, I added to following to the Make file (to deal with the encoding issue), but got the same error

#!/usr/bin/env python

# -*- coding: utf-8 -*-

How should I handle this?
