i Have 2 programs of Matlab but I need these codes in python code.

Data Extract(Matlab code)

function [Allvals]= DataExtract(fname, Fs, nfft,fnum, classl, classval) data = csvread(fname);

Allvals=[];

% % Visualization

% subplot(2,1,1);

% h1 = plot(data(:,7:8));

% %---- % Window parameters

wlen=128;

olap = 20;

ind = 1;

hold on;

num=1;

while ind+wlen < size(data,1) hold on;

t = ind:ind+wlen-1;

dSliceA=data(t,7);

dSliceG=data(t,8);

% % Visualize

% subplot(2,1,1);

% h2 = plot(t,dSliceA,'g');

% subplot(2,1,1);

% h3 = plot(t,dSliceG,'g');

% title([classl,' Iteration #',num2str(fnum)]);

% pause(0.1);

% delete(h2); delete(h3);

% % % -------- %

ind = ind+olap;

% Frequency Analysis (Accelerometer);

x = dSliceA - mean(dSliceA);

y = fft(x,nfft);

y = abs(y.^2);

y = y(1:1+nfft/2);

[v,k] = max(y);

f_scale = (0:nfft/2)* Fs/nfft;

festA = f_scale(k);

% Frequency Analysis (Gyroscope);

x = dSliceG - mean(dSliceG);

y = fft(x,nfft);

y = abs(y.^2);

y = y(1:1+nfft/2);

[v,k] = max(y);

f_scale = (0:nfft/2)* Fs/nfft;

festG = f_scale(k);

% Extract Values Accvals(num,:)=[max(abs(dSliceA)),min(abs(dSliceA)), mean(dSliceA), std(dSliceA), festA];

Gyrovals(num,:)=[max(abs(dSliceG)),min(abs(dSliceG)), mean(dSliceG), std(dSliceG), festG];

Allvals=[Allvals;

[Accvals(num,:), Gyrovals(num,:), classval]];

% % Visualization

% subplot(2,1,2);

% stem(num,Allvals(num,5));

% hold on;

% num=num+1;

%------------------ end end

Getdata(Matlab code)

% Get Data from files

% Acquiring Statistics from Parkinson's Motion Data using Moving Window

% Data Sampled at 20 Hz

% Received Data has 8 columns:

% Acc_x, Acc_y, Acc_z, Gyro_X, Gyro_y, Gyro_z,Acc_Norm, Gyro_norm clear all;

close all;

clc;

Fs = 20;

nfft = 64;

classes = {'Intentional', 'Rest', 'Tremor'};

% Switch to directory dirAll ='C:\Program Files\MATLAB\Work\Parkinsons\Datasets';

Values = [];

for i = 3:3 cd([dirAll,'\',classes{i}]);

files = dir('*.csv');

%Loads into structure for file = 1:length(files)

% i=10; fname = files(file).name;

Avals=DataExtract(fname,Fs,nfft,file, classes{i},i);

close;

disp([classes{i},' Iteration #',num2str(file),' done!']);

Values = [Values;Avals]; end cd(dirAll);

csvwrite([classes{i},'.csv'],Values);

display(['Completed writing CSV file for ', classes{i}]);

end csvwrite('Alldata.csv',Values);

display('Completed writing CSV file for all data');

Hi @B.V Lavanya,

I understand that you want to convert MATLAB code to Python.

Kindly refer to the following MATLAB Answers :

1. To call MATLAB code from Python: https://www.mathworks.com/matlabcentral/answers/426258-how-to-convert-the-matlab-code-into-the-python
2. To convert MATLAB code to Python: https://www.mathworks.com/matlabcentral/answers/1904000-convert-matlab-code-to-python

I hope this helps!
