Generate Music using Matlab The music notes can be generated

Generate Music using Matlab: The music notes can be generated using sinusoids with specific frequencies; e.g., the middle C can be obtained as: cos(2ft), where f = 261.63 Hz. See, e.g., http://www.intmath.com/trigonometric-graphs/music.php for more details. Please code a function with the prototype: function x = tone(f, fs, td) to produce the signals for the music notes, where f is the frequency for the note, fs = 15000 Hz is the sampling frequency, and td is the time duration for the note, e.g., td = 0.4 sec. Then make the music for one of your favorite songs using this function and the Matlab function sound(), as we showed in the class. The deliverable for this project is a .doc file containing your design procedure for this music player and all the .m files.
