Matlab Easter Egg - Make It Sing Faster/Slower

1. Do the above "Make it sing" by Robbert Lagerweij by typing "lalala"
2. Note again you must have matlab able to produce sound for this to work
3. Type in "sound(y,16000)" and it should sing a little bit faster
4. Note you can replace the 16000 above with any number you like, it's the sampling frequency
5. If you want to do the default then use 8192 or Fs
