댓글:Ryan Rolick2017년 1월 11일 I estimated cross correlation between two monthly time series like: [xc,lag]=xcorr(y1,y2) [mx,mind]=max(abs(xc)); delay =lag(mind); I got the value as 1 what does it meaning i want the lag in time unit how to get..please help ...

댓글:Image Analyst2017년 4월 26일 MATLAB Online에서 열기 Hello, I need to align two signals presented below: I use xcorr function: [acor,lag] = xcorr(PROFILE2,PROFILE1); [~,I] = max(abs(acor)); lagDiff = lag(I) ...
Open in MATLAB Online with small edits: assuming the inputs are column vectors ThemeCopy function [R,L,pvalue] = nanxcorr(s1,s2,Lag) % function [L, R,pvalue] = nanxcorr (s1, s2, Lag); % Function that allows obtaining the cross-correlation % of a pair of ...
xcorr and xcov Functions: Compute cross-correlation and cross-covariance in core MATLAB You can now compute the cross-correlation and cross-covariance of data using MATLAB. Previously, xcorr and xcov were only available in the Signal Processing Toolbox™. d...
c) Using the unfiltered simulated data, one time-series of each pair was allowed to shift forwards and backwards in time (using the xcorr function in Matlab) and the (absolute) maximum correlation across the shifts was recorded. Histograms of the resulting maximum correlation values are plotted ...
Image Analyst 2013 年 5 月 6 日 You'd have to use normxcorr2() instead of corr2(), otherwise just some uniform image of 255 will give a higher correlation than the correlation of the image with itself, since it's just multiplying and summing. サインインしてコメントする。サ...
Here, the scaling of individual player performance is done with two diverse normalization methods known as Standard and Xcorr normalization to reduce the dependency over the environmental condition during fitness measurements. Unaffected by the weather, a revolutionary machine learning approach is intended ...
xcAB = xcorr([A,B],numel(A)/2,'unbiased'); plot(fftshift(ifft((fft(A).*conj(fft(B)))/numel(A),'r') hold on plot(xcAB(:,2)) The "only" difference between this and what you get with the spectrogram/wavelet spectra is that those methods cuts the data into shorter (p...
For cross-correlation of the activity traces with the treadmill velocity, the treadmill velocity was convolved with a Ca2+ kernel and cross-correlation was computed using the ‘xcorr’ function. Mutual information was calculated under the Gaussian assumption, I(X;Y) = 1/2 log(|Σ(X)|/| Σ...
