differences between 2 arrays

[millansf]

I have 2 arrays of 4000 samples, the samples are more or less the same but in the second array they are shifted a number. How can I get this number?

For example, the two arrays could be:

[1 2 3 4 5 6 7]   [0.2 0.1 0.2 1.1 2.1 3 4.2 5.1 6.2 6.9 ]

Thanks

if the 2 arrays are identical but "shifted", you can use the "search 1D array.

however, from your example it look they are quite different. what is the overall purpose?

[millansf]

No, the arrays are not identical.

The thing is, I have 2 microphones in two diferent position of a room, I transmit a burst, and I get samples of this signal, so this samples are very similar but shifted, and I want to get this "shift"...

Thanks

you might need some different function for that. i understand you look for the phase difference between the 2 signals.

in the signal processing pallette, you have the waveform measurment subpallette. browse there as well as example related.

one particular function i have in mind is the frequency response function, which will give you the phase between 2 signals.

does it help?
