Recombine cell arrays to produce a new image

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.

I = imread('hide.jpg');
[rows, columns, planes] = size(I);
 
blockSizeR = 50; % Rows in block.
blockSizeC = 50; % Columns in block.
FullBlockRows = floor(rows / blockSizeR);
blockVectorR = [blockSizeR * ones(1, FullBlockRows), rem(rows, blockSizeR)];
% Figure out the size of each block in columns.
FullBlockColums = floor(columns / blockSizeC);
blockVectorC = [blockSizeC * ones(1, FullBlockColums), rem(columns, blockSizeC)];
% Create the cell array
Cellarray = mat2cell(I, blockVectorR, blockVectorC, planes);
 
 
% Display all the blocks.
count =1;
plotIndex = 1;
numPlotsR = size(Cellarray, 1);
numPlotsC = size(Cellarray, 2);

    for c = 1 : numPlotsC
        if bitget(c,1)
            fprintf('plotindex = %d,   c=%d, r=%d\n', plotIndex, c, r);
        else
            fprintf('noooooo you odd bitch\n')
        end
        % Plot consecutively.

Hi Kalyan, it's not working

F=cell2mat(rgbBlock);

imshow(F)

Brace indexing is not supported for variables of this type.

Error in cell2mat (line 42)

cellclass = class(c{1});

Error in blocktest (line 47)

F=cell2mat(rgbBlock);
