I have a matlab code for image 300X720 pixel has been divide (split) to 4X12 parts (the total is 48 parts), and I would like to to do the following step which I couldn't do it:

first, I want to make a loop (insert 6 image instead of one image).
second, I want to save each image output (48 parts for each image) in different file (folder).

Here my last matlab code for one image splited to 4X12 (48 parts).

clc;    % Clear the command window.
format compact;
workspace;  % Make sure the workspace panel is showing.
fontSize = 20;
% Read in a standard MATLAB gray scale demo image.
folder = fullfile(matlabroot, '\toolbox\images\imdemos');
baseFileName = ('C:\Users\HOME\Desktop\image.tif');
% Get the full filename, with path prepended.
fullFileName = fullfile(folder, baseFileName);
if ~exist(fullFileName, 'file')
  % Didn't find it there.  Check the search path for it.
  fullFileName = baseFileName; % No path this time.
  if ~exist(fullFileName, 'file')
    % Still didn't find it.  Alert user.
    errorMessage = sprintf('Error: %s does not exist.', fullFileName);
    uiwait(warndlg(errorMessage));
    return;
  end
end
grayImage=imread(fullFileName);
grayImage = rgb2gray(grayImage);
% Get the dimensions of the image.  numberOfColorBands should be = 1.
[rows1 columns1 numberOfColorBands1] = size(grayImage);
% Resize the image to be 300x720
grayImage = imresize(grayImage, [300, 720]);
% Get the dimensions of the image.  numberOfColorBands should be = 1.
[rows2 columns2 numberOfColorBands2] = size(grayImage);
figure;
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[.05 .05 .9 .9]);
set(gcf,'name','Demo by ImageAnalyst','numbertitle','off') 
folder = pwd;
plotIndex = 1;
for i=1:4
  % Extract out the small image.
  row1 = (i-1)*75+1;
  row2 = row1 + 74;
      for j=1:12
          column1 = (j-1)*60+1;
          column2 = column1 + 59;
          smallImage = grayImage(row1:row2, column1:column2);
    
    % Display the small image.
    subplot(4, 12, plotIndex);
    imshow(smallImage);
    caption = sprintf('Image #%d', plotIndex);
    title(caption);
    plotIndex = plotIndex + 1;
    
    % Save the small image to disk.
    baseFileName=sprintf('image%i.jpg',i,'image%j.jpg',j);
      fullFileName = fullfile(folder, baseFileName);
    fprintf('Saving %s\n', fullFileName);
     imwrite(smallImage, fullFileName);
      end;
  end;
