Hi, everyone! I need a help to convert python code to matlab about mie scattering in homogenous sphere, below is my python code. I add 'z' variable to get the value of scattering.
import PyMieScatt as ps
mie = ps.MieQ(1.525+0.0011j,450,300,asDict=True) %index refractive, wavelength, diameter of particle
z = mie['Qsca']

PyMieScatt is not a trivial program. If you want something similar to use in native Matlab, you will probably have to find an implementation somewhere else, or write your own. If you want to try using python from Matlab, you can follow the below steps (but Matlab freezes for me when I try this).
  1. Have a supported version of python installed: CPython 2.7, 3.7, 3.8, or 3.9
  2. In Matlab, set it up with pyenv, e.g.: pyenv('Version','path/to/supportedVersion')
  3. Run (do not import):
mie = py.PyMieScatt.MieQ(1.525+0.0011j,450,300,asDict=True);

With Mie.py in your Matlab path and pyenv set up correctly, do:
mie = struct(py.Mie.MieQ(1.525+0.0011j,450,300,pyargs('asDict',true)))
z = mie.Qsca
