Error using sound (line 76) Index exceeds matrix dimensions.

Below is the code that I am trying to run, however I cant seem to sound my "song" even though I could sound my "test". The only difference between the 2 of them is just the difference of line 4, which can be played.

Can someone enlighten me on this issue? Thank you.

      A=sin(2*pi*440*(0:0.000125:0.5)); 
      B=sin(2*pi*493.88*(0:0.000125:0.5));
      B1 = sin(2*pi*493.88*(0:0.000125:1));
      B2=sin(2*pi*493.88*(0:0.000125:2));
      C5=sin(2*pi*523.25*(0:0.000125:0.5));
      C1=sin(2*pi*523.25*(0:0.000125:1));
      D=sin(2*pi*293.66*(0:0.000125:0.5));
      D5=sin(2*pi*587.33*(0:0.000125:0.5));
      E5=sin(2*pi*659.2*(0:0.000125:0.5));
      El=sin(2*pi*659.25*(0:0.000125:1));
      G=sin(2*pi*392.00*(0:0.000125:0.5));
      G1=sin(2*pi*392.00*(0:0.000125:1));
      As = sin(2*pi*466.16*(0:0.000125:0.5));
      pause=sin(2*pi*0*(0:0.000125:0.01));

      line1=[D,G,A,B1,B1,pause,B,As,B,G1,G1,pause];
      line2=[G,A,B,C1,El,pause,E5,D5,C5,B2,pause];
      line3=[G,A,B,C1,El,pause,E5,D5,C5,B,G1,pause];
      line4=[G,A,B1,pause,C5,A,pause,A,B,G1];
      song=[line1,line2,line3,line4];
      test=[line1,line2,line3];
      sound(song);

After you do everything on the linked page, it’s necessary to close and then restart MATLAB (at least on Windows systems).

Step 3 says to close MATLAB ;-)

I missed that! (I was concentrating on getting the file in the correct directory.)

truly great answer and helps me a lot!
