I want to have a rgb matrix from the rgb values i am getting at each step of the for loop. And I want to create a new image with every pixel rgb data to be at the same location as the row and col in operation. My code is as follows:

numberOfImages=5;

finalRGBImageMatrix=zeros(1584,2780,3); for row=390:392 for col=498:500

                for i=1:numberOfImages
                    filename=[num2str(i), '.png'];
                    rgbImage=imread(filename, 'png');                      
                    R = rgbImage(row, col, 1);
                    G = rgbImage(row, col, 2);
                    B = rgbImage(row, col, 3);
                    RGBMatrix(i,:) =[R,G,B];
                end
                    for imageNumber=1:numberOfImages
                        match=0;
                        jitter=0;
                        for j=numberOfImages:-1:1   
                                RedChannelDifference=abs(double(RGBMatrix(j,1))-double(RGBMatrix(imageNumber,1)));
                                GreenChannelDifference=abs(double(RGBMatrix(j,2))-double(RGBMatrix(imageNumber,2)));
                                BlueChannelDifference=abs(double(RGBMatrix(j,3))-double(RGBMatrix(imageNumber,3)));
                                    if (RedChannelDifference+GreenChannelDifference+BlueChannelDifference)<=10
                                                jitter=jitter+RedChannelDifference+GreenChannelDifference+BlueChannelDifference;
                                                match=match+1;
                                    end
                        end
                        match=match-1;
                        matchMatrixOfAllImages(imageNumber,:)=[match];
                    end
                    %fprintf('The maximum value of matches is : %d \n', max(matchMatrixOfAllImages(:)));
                    index=find(matchMatrixOfAllImages == max(matchMatrixOfAllImages(:)));
                     if size(index,1)>1
                         jitterMatrixOfAllImages(imageNumber,:)=[jitter];

                            end
