How do I display .mat file as an image in Matlab

Hi All Matlab users,

I have a .mat file ... I would like to convert it to png file but I have a problem with display it.

src_folder = 'D:/14.3D/1/';
dst_folder = 'D:/14.3D/1';
files = dir(fullfile(src_folder, 'OD.mat'));
% Loop through each file
for i = 1:length(files)
    % Load the .mat file
    load(fullfile(src_folder, files(i).name));
    % Convert the data to uint8
    I = reshape(uint16(linspace(0,65535,25)),[5 5])
    example_matrix = im2uint8(1);
    example_matrix = im2uint8(example_matrix);
    % Construct the destination file name
    [~, name, ~] = fileparts(files(i).name);
    dst_file = fullfile(dst_folder, [name '.png']);
    % Try to save the image
    try
        imwrite(example_matrix, dst_file);
        disp(['Image ' name ' saved successfully']);
    catch
        disp(['Error saving image ' name]);
    end
end

The image show it stae is empy. Could someone help me please ? I would appreciate for any help.

Attach atleast one mat file data, so that we can check it.

example_matrix = im2uint8(1);

should be (I) instead of (1)
