for k = 1:22
    pic2read = strcat(num2str(k),'.dcm');
    if k<10
        pic2read = strcat('0',pic2read);
    end
    imread(pic2read);
end

Thank You Soooo much

One more thing please!;

after doing some processing on those 22 images I want to save them in a single .mat file;

how it will be please! urgent

[David Sanchez]

use the save option.

doc save

will tell you all the saving option available.

It will be something like:

save('my_data_file.mat','your_images_array')

Adding the '0' manually is a really inefficient solution. See Andrei's much nicer and faster sprintf method.

Answer 2

for k = 1:22,  imread(sprintf('%02d.dcm',k)); end
