if I have multiple sounds that already have specific tones and they're named: y0,y1,y2,y3,y4,y5,y6,y7,y8,y9
how can I make them play one after another without overlapping? the input is random so if the user types in:1,2,3,4 then the sounds y1,y2,y3,and y4 should be played one after the other. Thank you!

prompt = 'Enter atleast 10 numbers: ';
str='0';
while length(regexp(str,'\d'))~=10
str = input(prompt,'s');
end
N=length(str);
count=1;
for k=1:N
m=str2double(str(k));
if isnan(m)==0
str(count)=k;
count=count+1;
numbers = cell2mat(sscanf((str),'k'))
disp(m)
end
end
%sound 1
fs=8192;
T=.5;
t=0:(1/fs):T;
y1=cos(2*pi*1209*t)+cos(2*pi*697*t);
sound(y1,fs);
pause(.5);
%sound 2
fs=8192;
T=.5;
t=0:(1/fs):T;
y2=cos(2*pi*1336*t)+cos(2*pi*697*t);
sound(y2,fs);
pause(.5);
%sound 3
fs=8192;
T=.5;
t=0:(1/fs):T;
y3=cos(2*pi*1477*t)+cos(2*pi*697*t);
sound(y3,fs);
pause(.5);
%sound 4
fs=8192;
T=.5;
t=0:(1/fs):T;
y4=cos(2*pi*1209*t)+cos(2*pi*770*t);
sound(y4,fs);
pause(.5);
%sound 5
fs=8192;
T=.5;
t=0:(1/fs):T;
y5=cos(2*pi*1336*t)+cos(2*pi*770*t);
sound(y5,fs);
pause(.5);
%sound 6
fs=8192;
T=.5;
t=0:(1/fs):T;
y6=cos(2*pi*1477*t)+cos(2*pi*770*t);
sound(y6,fs);
pause(.5);
%sound 7
fs=8192;
T=.5;
t=0:(1/fs):T;
y7=cos(2*pi*1209*t)+cos(2*pi*852*t);
sound(y7,fs);
pause(.5);
%sound 8
fs=8192;
T=.5;
t=0:(1/fs):T;
y8=cos(2*pi*1336*t)+cos(2*pi*852*t);
sound(y8,fs);
pause(.5);
%sound 9
fs=8192;
T=.5;
t=0:(1/fs):T;
y9=cos(2*pi*1477*t)+cos(2*pi*852*t);
sound(y9,fs);
pause(.5);
%sound 0
fs=8192;
T=.5;
t=0:(1/fs):T;
y0=cos(2*pi*1336*t)+cos(2*pi*941*t);
sound(y0,fs);
pause(.5);
this is my whole code and I'm having trouble figuring out how I can get one sound to play after the other depending on what the user inputs so if the user inputs: 4560987321 then I want it to play the sounds in order (y4,y5,y6,y0,y9,y8,y7,y3,y2,y1) thank you!

You need to use the playblocking function to prevent them from overlapping. This is part of the audioplayer functions, so you should have access to it. See the documentation for details.

Just compute the time T (secs) the file lasts by using sample rate information and number of samples. Then, pause the for loop for the number of seconds (plus 1 if you want delay time of 1 sec. in between). For randomness, arrange files in array and randomize on indeces:
s(1)=load('gong.mat','y','Fs');
s(2)=load('handel.mat','y','Fs');
randsel = randperm(numel(s));
for x=s(randsel)
sound(x.y,x.Fs);
T = numel(x.y)/x.Fs;
pause(T+1);
end

I understand but how could I get the sounds to play in consecutive order if I get an input like: 5910 and each number has it's own sound

Are you asking how to transform number (say) 5910 into array [5,9,1,0]?
