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

[Paulo Silva]

please provide one example of the data you want to compare

[andoni]

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..

[Paulo Silva]

almost there, now please see what's inside signals

[andoni]

inside there are 5 fields:

values: <28884x1 double> inside this--> 0

6

5

dimensions: 1

label

title

[Paulo Silva]

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)

Thanks!!

[andoni]

and now do you know how to say in what index is the diference?
