Hello,
First thanks for 'us' reply.I tried the code to sort the images by creation date .I am giving it below.
==>
indir = uigetdir();
cd(indir);
allimages=dir('*.png');
[ai,ix]=sort([allimages.datenum]);
len = length(ai);
msgbox(num2str(len));
len1 = length(ix);
msgbox(num2str(len1));
%flst={flst(ix).name}.';
% for i=1:len
% aiout = ai(i);
% ixout = ix(i);
% x=num2str(aiout);
% y=num2str(ixout);
% msgbox(strcat(x,y));
% end
for k = 1:length(allimages)
fileno = ix(k);
filename = allimages(fileno).name;
data1 = imread(filename);
figure,imshow(data1);
end

I am getting an error as below.

==>
??? Reference to non-existent field 'datenum'.

Error in ==> newproblem at 5
[ai,ix]=sort([allimages.datenum]);

I am using matlab of version 7.0.0.1 . Could anyone help me in this.

regards,
Vasu D.
