How to save data as image as one pixel using MATLAB

Hello everyone, i hope you are doing well.

I am going to save the data as image format i have written the following code as one of the answer on MATLAB.

The dataset is Dats.mat file the Original data first row is

• Original Data.jpg

The Image generated from the data is

• ImagefromData.jpg

The save is generated same like the data but when i compared the values the first value of the dataset is 173 as shown in

• FirstValue.PNG

But when i look at the first value of image it is 173.5 and 172.5

• Firstvalueofimage.PNG

but the value should be only 173

How can i modified this code to save 173 value as 173 pixel value

Can anybody help me in this

labels1000= repelem(eye(1,1),1000,1);

tempdir=mkdir('DATASET1');
classdir=mkdir('DATASET1','OneClass');
dataDirectory = fullfile('C:\Users\DELL\Documents\MATLAB\Examples\R2021b\phased\ModClassificationOfRadarAndCommSignalsExample\NewDataset\DatasetGeneration\DATASET1\SixClass');
disp("Data file directory is " + dataDirectory)
[labelNums,~,labelIdx] = unique(labels1000,'rows');
labelStrs = {'Class'};
%% make the folders
for ii = 1:numel(labelStrs)
    labelStr = labelStrs{ii};
    if ~isfolder(labelStr)
        mkdir(dataDirectory,labelStr);
    end
end
%% create grayscale shapes that resemble the data
[numImages, lenImage] = size(Dataset1000);
imSz = 1000; % assuming images are 1000x1000
imbg = false(imSz);                                  % background "color"
imfg = ~imbg(1,1);                                  % forground "color"
imSizeOut=[1000 1000];                                % ImageSize
for imNum = 1:numImages        
    imData = round(Dataset1000(imNum,:));  % get pattern
    
    [~,Y] = meshgrid(1:imSz); % make a grid
    
    % black and white image
    BW = imbg;
    BW(Y==imData)=imfg;
    
    % resize (from 1000x1000)
    BW=imbinarize(imresize(uint8(BW),imSizeOut));
    % convert to uint8 (0 255)
    im = im2uint8(BW);
    %im = flipud(im);
    folderName = labelStrs{labelIdx(imNum)};
    im_FullFilename = fullfile(dataDirectory,folderName,sprintf('imageclass_%06g.png',imNum));
    imwrite(im,im_FullFilename);
end
