_____________________________________________________
OTHER FUNCITONS
1. wm.m : dictionary file, transfer 26 small English letters to binary digits and extand the watermarked information to circular expression.
2. dwm.m : decoding function, the output is a circularly expressed sequence with marked information
3. findwm.m : find the exact watermarked information from the circularly expressed sequence
4. play_f.m : random playing function for subjective test of frequency masking
5. play_p.m : random playing function for subjective test of phase-shift masking
6. play_e.m : random playing function for subjective test of echo masking
