If you have the image processing toolbox you can use the following commands:

im1=imread('image1.tiff')
im2=imread('image2.tiff')
im3=imread('image3.tiff')
HDR = makehdr(im1,im2,im3)

Hello Thomas, thank you for your answer...

Can you explain what is "Processing toolbox"?

It's a software package you have to buy: http://www.mathworks.com/products/image/. It may already be included if you bought certain licenses, like the student license. Type "ver" on the command line to check for it, or run this code in your script:

% Check that user has the Image Processing Toolbox installed.
hasIPT = license('test', 'image_toolbox');
if ~hasIPT
  % User does not have the toolbox installed.
  message = sprintf('Sorry, but you do not seem to have the Image Processing Toolbox.\nDo you want to try to continue anyway?');
  reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
  if strcmpi(reply, 'No')
    % User said No, so exit.
    return;
  end
end

Humm.. if I don't have processing toolbox how I can create a picture HDR?

I'm a little bit worried with this because I don't understand Matlab..

Thank you again!

Have a look at this project, browse through their code! http://cybertron.cg.tu-berlin.de/eitz/hdr/

If you are really new to Matlab I suggest you learn some basics first.
