Matlab program to play Star Spangled Banner - Rhea

Creating the Star Spangled Banner in MATLAB

Using the sound function in Matlab, we are able to create a song using sine waves with specific frequencies. Each note has certain frequency that corresponds to it and through sine waves and putting it into the sound function we are able to create a song.
