I have a folder which contain 17 images and are named like 1im,2im...17im. I am classified this images into two classes 1 and 2. so I got 12 images are in group 1 and 5 images are in group 2. I want to read the images which are classified in group 1. p gives the indices of the image which are classified into first group. I tried the following code but it does'nt give exact answer. please help me.thanks in advance
p=find(Group==1);
disp(p);
A=[];
for ii=1:17
A{ii} = imread(['H:\dataa\try4\' num2str(ii) 'im' '.bmp']);
figure;imshow(A{p});
end

How do you know what filenames correspond to Group? Is Group created with the same 17 files in the very same order as you're making up the filename strings? If so, do this
p= Group==1 % Logical vector.
A=cell(1, length(Group)); % Preallocate
for k = 1 : length(Group)
thisFilename = sprintf('H:\dataa\try4\%dim.bmp', k);
if exist(thisFilename, 'file')
A{k} = imread(thisFilename);
% Display it only if it's in group 1
subplot(4, 5, k);
if p(k)
imshow(A{k});
end
else
message = sprintf('%s does not exist', thisFilename);
uiwait(warndlg(message));
end
end
