This function computes the correlation as generally defined in signal processing texts: c_ {av} [k] = sum_n a [n+k] * conj (v [n]) Syntax : numpy.correlate (a, v, mode = ‘valid’) Parameters : a, v : [array_like] Input sequences.
WebFeb 24, 2014 · c = xcorr (x, y) computes the cross-correlation function between two scalar signals (given as vectors), and c = xcorr (x) computes the auto-correlation function of a signal if x is a vector, and the auto- and cross-correlation functions between all columns of x if it is a matrix. If x is of size n x p, then c is of size 2*n-1 x p^2. When you write WebCross-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 …
