Wave Packets (a) Create a wave by adding two different waves by using Matlab, but different combination than those we used in the class. Paste the output graph (and also the code). Any two waves can be chosen, but explain the difference compared to the original wave packet we obtained in the class. You can modify the code I used in the class, or build something from scratch. (b) Add as much waves as you want (minimum:3), using Matlab. Explain...
