So I have to make a song on matlab and then set up sine waves that correspond to the notes on the scale. The notes are AGGABCFG. can someone help me with this?

Look at these links
For your case
notes={'C' 'C#' 'D' 'Eb' 'E' 'F' 'F#' 'G' 'G#' 'A' 'Bb' 'B'}
freq=[261.6 277.2 293.7 311.1 329.6 349.2...
370.0 392.0 415.3 440.0 466.2 493.9]
song={'A' 'G' 'G' 'A' 'B' 'C' 'F' 'G'} % your song
a=[]
for k=1:numel(song)
note_value=0:0.000125:0.5 % You can change the note duration
a=[a sin(2*pi* freq(strcmp(notes,song{k}))*note_value)];
end
sound(a)

I am doing research for my graduation project, but I could not reach enough code information.I want to assign music notes to computer keys for digital synthesizer. Can you write this code with adsr enveloping please?

This is not an answer to anything, but a direct request for someone to provide code to you to do your task. If this is research, will you give direct credit to the person who did the work for you when you hand in your project? Will their name be listed on front of your project as a direct contributor? Or, would you happily hand in someone else's efforts as your own?

You r right. I asked my problem wrong way. Can you help me write to assign computer keys to play music notes?
clear ;
close all;
fs=8500;
t=0:0.000117:3;
note_do= sin(2*pi*261.6*t);
note_re= sin(2*pi*293.7*t);
note_mi= sin(2*pi*329.6*t);
note_fa= sin(2*pi*349.2*t);
note_sol= sin(2*pi*392*t);
note_la= sin(2*pi*440*t);
note_si= sin(2*pi*493.9*t);
note_do1= sin(2*pi*523.5*t);
y=note_do;
A = linspace(0, 0.9, (length(y)*0.10)); %rise 35% of signal
D = linspace(0.9, 0.7,(length(y)*0.05)); %drop of 5% of signal
S = linspace(0.7, 0.7,(length(y)*0.40)); %delay of 40% of signal
R = linspace(0.7, 0,(length(y)*0.20)); %drop of 25% of signal
ADSR = [A D S R] ;
x = zeros(size(y));
x(1:length(ADSR)) = ADSR;
tone=y.* x;
sound(tone,fs);
