How to convert python code to Matlab?

Is there way to convert this python code to matlab code?

how can i convert python code to matlab???

this is the code that I want to convert:

import os

os.environ("KMP_DUPLICATE_LIB_OK") = "TRUE"; %%aggiungo una variabile ambiente

from sklearn.cluster import estimate_bandwidth

from sklearn import metrics

def estimate_bandwidth_meanshift(features, perc, quantile=0.5):

print('Start estimating bandwidth -------------------------------------')

bandwidth = estimate_bandwidth(features, quantile=quantile, n_samples = int(features.shape(0)*perc/100))

print('End estimating bandwidth ---------------------------------------')

return bandwidth

def getNMI(prediction, gt):

return metrics.normalized_mutual_info_score(gt, prediction)

def getARI(prediction, gt):

return metrics.adjusted_rand_score(gt, prediction)

There is no automated conversion possible.

You have two options:

1. Look up the meaning of each function and implement the working of the code in Matlab.
2. Run the python code from within Matlab.

Which did you try?

[filippo gistri]

I tried to run python on matlab, but it didn't work.

If i run, matlab return this error:

Error using python_utility><module>

Error in <frozen importlib>_call_with_frames_removed (line 241)

Error in <frozen importlib>exec_module (line 883)

Error in <frozen importlib>_load_unlocked (line 688)

Error in <frozen importlib>_find_and_load_unlocked (line 1006)

Error in <frozen importlib>_find_and_load (line 1027)

Error in <frozen importlib>_gcd_import (line 1050)

Error in __init__>import_module (line 126)

I don't work with the Python link enough to understand this error without seeing the code you tried.

Hi!

There is no direct way to convert python code to MATLAB.

There are two approaches:

• You have to directly write the code from scratch.
• You can use MATLB API to call python script in MATLAB
• https://www.mathworks.com/help/matlab/call-python-libraries.html
• As of MATLAB 8.4(R2014b) you can call Python directly from MATLAB

Refer to the following MATLAB answers post with similar issue:

[rushabh rupani]

Converting Python code to Matlab can be a complex process, as the two languages have different syntax and libraries.

You can use the Py2Mat library to accomplish your desired result.

Answer 4

[Anoy Chowdhury]

Only some commands like

py.list({'This','is a','list'}) 

are recommendable to use from python. In the other hand, you can create a full funcion in python script / function and call it with:

pyrun('my_python_callback')

However, trying to "convert" a python script line by line to MATLAB is pointless. To give you a context, is equivalent to try to convert to python some script which includes:

%...
sys = armax(tt2,[na nb nc nk])
%...

Since armax belongs to a toolbox (System Identification) it would be extremely complicated and unpractical.

If you want to use a python library as sklearn.cluster, stay in python, the only reason to import to MATLAB should be importing a python environment to interact with an MATLAB , for example an MATLAB AI agent:

classdef mountain_car_1 < rl.env.MATLABEnvironment
  properties
    open_env = py.gym.make('MountainCar-v0'); %% IMPORT PYTHON OPEN AI ENVIRONMENT
  end
  methods
    function this = mountain_car_1()
      ObservationInfo = rlNumericSpec([2 1]);
      ObservationInfo.Name = 'MountainCar Descreet';
      ObservationInfo.Description = 'Position, Velocity';
      ActionInfo = rlFiniteSetSpec([0 1 2]);
      ActionInfo.Name = 'Acceleration direction';
      this = [e-mail](ObservationInfo,ActionInfo);
    end
    function [Observation,Reward,IsDone,LoggedSignals] = step(this,Action)
      result = cell(this.open_env.step(int16(Action))); 
      Observation = double(result{1})'; 
      Reward = double(result{2});
      IsDone = double(result{3});
      LoggedSignals = [];
      if (Observation(1)>=0.4)
            Reward = 0;
            IsDone = 1;
      end
    end
    function InitialObservation = reset(this)
      result = this.open_env.reset();
      InitialObservation = double(result)'; 
    end
  end
end 

In the previous example, if you had installed Python 3.10, and OpenAIGym, you can import the desired environment to MATLAB and interact both with the used and a potencial AI Bot.
