I want to ask, how to use natsortfiles to sort alphanumerically overlaying plots in one figure? I find it difficult to match one plot to another because they have different directories and filenames

This is my code

% E = folder cropped greyscale
X = 'C:\Users\Lenovo\Documents\new matlab\hasil cacah 2\croppedk';
S = dir(fullfile(X,'*.jpg'));
contents = natsortfiles({S.name});
% I = folder contour
Y = 'C:\Users\Lenovo\Documents\new matlab\hasil cacah 2\contourk';
L = dir(fullfile(Y,'*.jpg'));
isi = natsortfiles({L.name});
for k = 1:numel(contents)
    for i =1:numel(isi)
    E = imread(fullfile(X,contents{k}));
  % Make a truecolor all-green image.
    green = cat(3, zeros(size(E)), ones(size(E)), zeros(size(E)));
    hold on
    h = imshow(green);
    hold off
    I = imread(fullfile(Y,isi{i}));
    % green image.
    set(h, 'AlphaData', I)
    % Use our influence map image as the AlphaData for the solid
        path = 'C:\Users\Lenovo\Documents\new matlab\hasil cacah 2\croppedk\zPlot';
    saveas(gcf,fullfile(path,['zPlot' int2str(k) '.jpg']));
    end
end

I want to overlay plots from different folders, folder 1 has filenames such as "gs1", "gs2" ,"gs3" ,"gs4" and folder 2 : "ax1"," ax2", "ax3" ,"ax4" so that i can overlay "gs1" with "ax1" and save as "z1", "gs2" with "ax2" and save as "z2", and so on.

Sorry about the confusion, yes I wanted to overlay plots from different folders, folder 1 has filenames such as "gs1", "gs2" ,"gs3" ,"gs4" and folder 2 : "ax1"," ax2", "ax3" ,"ax4" so that i can overlay "gs1" with "ax1" and save as "z1", "gs2" with "ax2" and save as "z2", and so on.

How can I achieve this? Thank you in advance, Stephen.
