Pentagram notation for cross correlation
Web7. jan 2024 · Cross Correlation Function. The cross correlation function between two different signals is defined as the measure of similarity or coherence between one signal and the time delayed version of another signal. The cross correlation function is defined separately for energy (or aperiodic) signals and power or periodic signals. Webc = xcorr2 (a,b) returns the cross-correlation of matrices a and b with no scaling. xcorr2 is the two-dimensional version of xcorr. c = xcorr2 (a) is the autocorrelation matrix of input matrix a. This syntax is equivalent to xcorr2 (a,a). Examples collapse all Output Matrix Size and Element Computation Create two matrices, M1 and M2.
