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. WebMar 25, 2024 · Therefore, the cross-correlation spectral kurtosis index function is designed based on the advantages of the kurtosis function and the cross-correlation function to quantitatively evaluate the detection ability of the bearing fault system under the background of complex noise in the frequency domain, as is expressed below: 24 inch plastic terracotta pots WebDetails.
