I have a project on digital image watermarking based on DCT algorithm. For the Image quality i check the PSNR of image and I want to print the value of PSNR in gui.

If it is to go into a graph then use text()
Otherwise use a uicontrol of style 'text', and set() the String property to the text you want to display.

PSNR = 32.1343;
text(57, 13, sprintf('%g', PSNR))
