Hi, I've split an image into blocks

for testing ive skipped all odd blocks

now how to i recombine all cells to create the a new picture with all the cells

plotIndex = 1;
numPlotsR = size(Cellarray, 1);
numPlotsC = size(Cellarray, 2);
for r = 1 : numPlotsR
  for c = 1 : numPlotsC
      if bitget(c,1)
    fprintf('plotindex = %d,   c=%d, r=%d\n', plotIndex, c, r);
      else
         fprintf('noooooo\n')
      end
    % Plot consecutively.
    if bitget(c,1)
    subplot(numPlotsR, numPlotsC, plotIndex);
    plotIndex = plotIndex +1
  continue;
    end
    % Extract the numerical array out of the cell
    rgbBlock = Cellarray{r,c};
    imshow(rgbBlock); % Could call imshow(ca{r,c})
    [rowsB, columnsB, numberOfColorBandsB] = size(rgbBlock);
    caption = sprintf('B#%d/%d', ...
      plotIndex, numPlotsR*numPlotsC);
    title(caption);
    drawnow;
    % Increment the subplot to the next location.
    plotIndex = plotIndex + 1;
  end
end

What is Cellarray? You forgot to include the first part of your program!

To properly indent your code, back in MATLAB (not here), type control-a (to select all) then type control-i (to properly indent). Now you can copy and paste the code here and not have it look like a total mess.
