Try psnr() and ssim(), both in the Image Processing Toolbox. See wikipedia for definitions.

I don't have the details. I don't already have the code just ready to hand over to you. Really, I don't. The details can be found in the link. Did you drill down into any of the links?

thank you for your reply in my case, the two images are the results, so I don't have a reference image how I can say, with the fonctions that you have provided me, this image is more good than the other
