Coding the Star Spangled Banner in MATLAB
Created by Sophia Gould
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.
