How to Calculate PSNR (Peak Signal to Noise Ratio) in MATLAB?

Peak-Signal to Noise Ratio (PSNR)
1. The PSNR is most commonly used as a measure of quality of reconstruction of lossy compression codec’s (e.g., for image compression).
2. The signal in this case is the original data, and the noise is the error introduced by compression.
