Webr = xcorr (x,y) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag. If x and y have different lengths, the function appends zeros to the end of the shorter vector so it has the same length as the other. add-ons for minecraft WebSep 10, 2024 · This looks like an ideal application for the cross correlation function, which will show the correlation between the two waveforms for every time offset between the two.
