Matlab kernel do not update python functions

Hello,

I'm using Python in Matlab and when I import librarys such as numpy or pandas the code doesnt run in Matlab.

This is my code in Python saved as test_matlab_python.py:

import numpy as np
def media(x,y,z,n):
    a = x*np.ones((n))
    b = y*np.ones((n))
    c= z*np.ones((n))
    med = a+b+c
    return med
    

and when I call in Matlab:

    mediana = py.test_matlab_python.media(5,3,8,10)

I got the error

Unable to resolve the name py.test_matlab_python.media.

But if I modify my python function to:

    def media(x,y,z):

    med = x+y+z
    return med

Then runs fine in Matlab, so I guess the problem is importing librarys, someone knows what I'm doing wrong?

Hi Jeniffer,

You can call Python libraries from MATLAB by installing a supported version with reference to the implementation for Python. MATLAB supports versions 2.7, 3.6, and 3.7. The version you install depends on the libraries you are using.

You can check the python version and change the default environment of Python interpreter by using "pyenv"

You can refer to these on how to call python from MATLAB.
