Matlab System Function and Terminal Runs differently

Question

I have a python code that I want to run in Matlab. It has an `import NumPy statement in it. The code runs without a problem in the terminal. But when I use Matlab system function It gives me the import error below.

Import error: No module named numpy

I'm using Python 3.9 on Matlab 2020b

My question is, why does the system function gives a different result than the Terminal itself?

I've tried to add the Python folder to MATLABPATH. But nothing changed.

Any suggestions?

Thanks in advance.
