interpretation of cross correlation between 2 signals?

Dear Matlab users,

in my way to seek the uncertainty level between two signals.

I performed a cross correlation between the 2 signals and I obtained the folowing plot

then I performed the dtw function to calculate the distance and it was 720

can I say that the data from the two signals are correlated, and what is the meaning of the value obtained using dtw, and how I can proceed further with uncertainty investigation.

I would highly apreciate your feedback

From the cross-correlation output, you can compute the delay between the two signals by detecting the indices of the maximum correlation

[cor,lag]=xcorr(SIGNAL1,SIGNAL2);

[~,I]=max(cor);

signallag=lag(I)

delay= (length(signal)-signallag)*1/Fs
