1. Sound function generally takes in two arguments, but you have given three that includes nbits.
2. A for loop is missing, and should be based on the size/length of y
for i=1:length(y);% y is size Nx1
temp=((y(i).^2)>=0);
end
sum(temp)% total energy

is your error still the same as shown in figure. If so it is because of line 4, change the format of function to
sound(y,fs);
If a different error is present send the snap.
