I am trying to use MATLAB with some Python integration. However, when I want to apply some changes to the python scripts/functions I need to restart MATLAB to use the updated version.

I have seen some threads/replies from the past but I was not sure if there is a new way to reload the scripts or clear old information.

(matlab script)

clc
clear
clear workspace
pyenv(Version = "C:\Users\m85830ak\Python\Matlab-python\.venv\Scripts\python.exe");
fun = @trial;
x0 = [150,120e5,7850000.0]
output = fun(x0)
A=[];
b=[];
Aeq=[];
beq=[];
lb = [150,74e5,74e5];
ub = [530,300e5,300e5];
[x,fval]= fmincon(fun,x0,A,b,Aeq,beq,lb,ub)

trial.m (matlab function file)

function a = trial(x)
a=py.matlab_file.turbine(x(1),x(2),x(3));
a = -a;
matlab_file.py (Python script)
from pyfluids import Fluid, FluidsList, Input
def turbine(tin, pin, pout):
    ntur = 85
    m=100
    turb_out = (
        Fluid(FluidsList.CarbonDioxide)
        .with_state(Input.temperature(tin), Input.pressure(pin))
        .expansion_to_pressure(pout, ntur)
    )
    turb_inlet = Fluid(FluidsList.CarbonDioxide).with_state(
        Input.temperature(tin), Input.pressure(pin)
    )
    delta_h = turb_inlet.enthalpy - turb_out.enthalpy
    w_tur = delta_h * m
    return w_tur

clear classes at the beginning of the script and

function a = trial(x)

mf = py.importlib.import_module("matlab_file");

py.importlib.reload(mf);

% y =[9, 4, 7, 5, 7, 4, 1, 5, 2, 3, 4];

a=mf.SQPOPT(x);

this reload is working.

在 MATLAB Online 中打开

py.reload(py.matlab_file);

Try using py.reload()
