Show diference between two signals

Hi, I have a telephone number save in a structure. This number is the correct number. In other structure i have a telephone number send and i want to compare the structures and show where the signals are diferent, i don`t want to show the complet signals, i want to show only the error if they are not equal.
Thanks

I get the tones obtained from a DTMF reciver and i compare with tones i generate. This tones i save in a structure that have:
time: <32801x1 double>
signals: <1x1 struct>
blockName: DTMFgenerator
is this what you want?
sorry about my english..

The part you are interested in is the values vector but it shouldn't be 0 like you say, try
plot(signals.values)
and see what appears.

Thanks I know that. I had badly explained.
What i want is compare the values of that structure with another one and when the values are diferent show a message that indicates that has been a error.

Do something similar to this
a=[0 5 6 7 8]
b=[0 5 6 8 8]
if any(~(a==b)) %if any index is diferent show error
disp('The signals aren't equal')
end
a and b are diferent signals like the example you provided (ie. a=signals.values)
