Hi,

firstly I would like to say that I am a real beginner in Matlab. It's the first time I use it and I'm trying to learn. So I'm truly sorry if the question I'm going to make could seem silly. Yet I'm not a complete beginner in coding: I know C, C++ and I'm trying to learn Python.

My question is very simple: if I have a .py file, let's say "Hello World", can I execute it from Matlab? If it is possible, how can I do that? Or can I just call the python functions?

Because I was wandering if I can exploit the knowledge I already have integrating it with the matlab environment.

I'm running matlab R2014b amd64 on Linux.

Thanks,

Cheers!

Simone

在 MATLAB Online 中打开

Simone - yes, if you have a simple .py file then you can execute it in MATLAB. For example, if your helloWorld.py file contains the following code

 import sys
 if __name__ == '__main__':
    sys.stdout.write('Hello World\n')

then you can execute this from MATLAB as

system('python helloWorld.py');

which would return

Hello World

But since you have R2014b, you can do a lot more with Python. See calling Python libraries and calling user-defined custom modules for more cool stuff that you can do.
