If the MATLAB Signal Processing Toolbox is available, a MATLAB routine called xcorr is available that does the same thing, but features a wider range of options. Crosscorrelation can be used for the problem in Example 2.13 to determine the similarity between a signal and a reference waveform ...
And further the cross correlation sequence value at zero lag is very close to 1. Now if I delay y with respect to x by two samples. ThemeCopy y = [zeros(1,2) x(1:end-2)]; [c,lags] = xcorr(y,x,'coeff'); stem(lags,c); I see that the cross correlation sequence peaks at ...
MATLAB’s xcorr method can be used to compute the cross-correlation of 2 time-sequences which are discrete in nature. The main aim of computing cross-correlation is to enable the use of a part of any incoming signal or beam to examine the transient evolution that is being produced by the...
Quantifying Cross-Correlation Between Vital Signs The maximum cross-correlation between two vital sign signals was measured over 10-min windows by first standardizing each signal (subtracting mean and dividing by standard deviation) and then using the Matlab function XCORR, with a lag time of −30...
c = normxcorr2(onion,peppers); surf(c) shadingflat Find the peak in cross-correlation. [ypeak,xpeak] = find(c==max(c(:))); Account for the padding thatnormxcorr2adds. yoffSet = ypeak-size(onion,1); xoffSet = xpeak-size(onion,2); ...

Sir Thanks For the Reply But I wana ask that is there anything that must be include in the code to read and perform xcorr on 64kb file and how the result are interpreted how will i come to know that the answer is right ?,,what does lags means how its divide the time ?This...
Perform cross-correlation, and display the result as a surface. c = normxcorr2(onion,peppers); surf(c) shadingflat Find the peak in cross-correlation. [ypeak,xpeak] = find(c==max(c(:))); Account for the padding thatnormxcorr2adds. ...
