for i=1:128 % totall images in the folder 128 images
img=readimage(imds,i);
ImgVector = img(:);

ImgVector = img3(:);
xlswrite('iVECTOR.xlsx',ImgVector);
end

Hi Furat,
As suggested in the xlswrite, use writematrix to save the images in excel sheet. Create the matrix for all 128 images first and then at once write all to excel sheet.
