how to store data in cell array

 I have 40 folders and each folder having 10 images, I have written one program for reading first five  

 images from 40 folders and stored in one cell array but I got the dimension i.e. 40 X 1 as given below

 40 X 40
 40 X 40
 .
 .
 40 X 40

 but I required the dimension of cell array i.e. 200 X 1 as given below

 1600 X 1
 1600 X 1
 .
 .
 1600 X 1

 function out=load_database()
 % We load the database the first time we run the program.

 persistent loaded;
 persistent w;
 if(isempty(loaded))
    v=zeros(10304,400);
    for i=1:40
        cd(strcat('s',num2str(i)));
        for j=1:5
            a=imread(strcat(num2str(j),'.bmp'));
                 %v(:,(i-1)*10+j)=reshape(a,size(a,1)*size(a,2),1);
            v = imresize(a,[40,40]);

        end

         w=uint8(v);                                                        

        faceData{i}=w;

         cd ..

    end   

end
loaded=1;  % Set 'loaded' to aviod loading the database again. 
out=faceData';

faceData = cell(40,5); % or cell(5,40)
for i=1:40
  for j=1:5
     % ... read v
     w = uint8(v);
     faceData{i,j} = w; % or faceData{j,i} = w;
  end
end
faceData = reshape(faceData,[],1);

thanks for giving an answer, now i get 200 x 1 cell array dimension but when I open cell array the output is 281 X 280 instead of that can i get inner cell value like 1600 X 1 1600 X 1 . . 1600 X 1

This is how you Read and resize your data.

If you have issue of resize an image read from file, you should ask in a separate question. We don't have your data to answer.

 sir, I have attached my database over here. I resize my image to 40 X  
 40, is it possible to reshape image into 1600 X 1 and store in cell  
 array

the read and try

thanks...

Alternatively you can also do

v = v(:)

after resizing into 40x40 to make it as a long vertical vector

 Now it works, thanks so much
