%Plays some of the mario bros song instead of the hail purdue because you might get 
%tired of hearing it over and over again

%Given

%The notes in the song
line= [e1,e1,e1,e1,p,c1,e1,e1,g1,g1,g1,g1, p, p, p, p,c1,c1,c1, g, p, p, e,e,p];
line1=[ a, a, b,p,bp, a, a, g, g, p,e1,e1,g1,a1,a1,f1,g1, p,e1,e1,c1,d1,b,b,b];

%combines the notes
note = [line line1];

%makes the sound
sound(note);

%makes the file titled as mario
song=[line,line1];
wavwrite(song,'Mario');

%to make the song twice as fast make delta faster
delta = 0:.000125*2:.125;

%to have y(t) = x(2t) we just multiply delta by 2
delta = delta*2;
