How to display many images using subplot in for loop

clear all;
close all;
%Load the folder in which input images exists
myfile=dir('E:\dataset\Input_images\*.jpg');
%Counts the number of files
numFiles = length(myfile)
numRows = ceil(sqrt(numFiles))
%Load the folder in which ground truth images exists
myfile1=dir('E:\dataset\GT\*.png');
%Counts the number of files
numFiles1 = length(myfile1)
numRows1 = ceil(sqrt(numFiles1))
figure;
for k = 1 : numFiles
    for j = 1 : numFiles1
        thisFileName = fullfile(myfile(k).folder, myfile(k).name);
        thisImage = imread(thisFileName);
        grey=rgb2gray(thisImage);
         
        thisFileName1 = fullfile(myfile1(k).folder, myfile1(k).name);
        thisImage1 = imread(thisFileName1);
            if (numRows == numRows1)
                %Segmentation of the image
                seg = imsubtract(thisImage1,grey);
                subplot(2,4,k);
                imshow(seg,[]);
                drawnow;
            end
    end
