Hello, please i tried to use the below code to apply empirical mode decomposition(emd) to each speech frame and after calculate the mean of the instrinsic mode decomposition of each frame for every file in the folder but i cannot, please i need help. Thank you very much.

clc;
clear all;
% Specify the folder where the files live.
myFolder = '/MATLAB Drive/AUDIO2';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(myFolder)
    errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
    uiwait(warndlg(errorMessage));
    myFolder = uigetdir(); % Ask for a new one.
    if myFolder == 0
         % User clicked Cancel
         return;
    end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '**/*.wav'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
AudioArray = cell(1, numel(theFiles));
i=1;
j=1;
o=1;
r=1;
u=1;
for k = 1 : numel(theFiles)   % NUMEL is more direct than LENGTH
    baseFileName  = theFiles(k).name;
    fullFileName  = fullfile(theFiles(k).folder, baseFileName);
    AudioArray{k} = audioread(fullFileName);
    [speech, fs] = audioread(fullFileName);
    %frame with buffer
    X = buffer(speech, 400, 50);
    [imf,residual] = emd(X,'MaxNumIMF',5);
    X1=imf(:,1);
    X2=imf(:,2);
    X3=imf(:,3);
    X4=imf(:,4);
    X5=imf(:,5);
% do framing
   
    
end
