要定量刻画这一需求,就需要计算两列波的互相关系数(Cross-Correlation, 简写为:CC)。 计算互相关系数的软件,代码很多,在此记录一下怎样用matlab自带函数xcorr来达到此目的,怕以后忘了。 接下来,本文首先说明一下相关的物理意义,再说一下怎么做,最后归纳一下互相关系数(CC)特点。
The true cross-covariance sequence of two jointly stationary random processes, xn and yn, is the cross-correlation of mean-removed sequences, ϕxy(m)=E{(xn+m−μx)(yn−μy)∗)}, where μx and μy are the mean values of the two stationary random processes, the asterisk denotes...
MATLAB’s xcorr method can be used to compute the cross-correlation of 2 time-sequences which are discrete in nature. The main aim of computing cross-correlation is to enable the use of a part of any incoming signal or beam to examine the transient evolution that is being produced by the...
2-D cross-correlation collapse all in pageSyntax c = xcorr2(a,b) c = xcorr2(a)Description c = xcorr2(a,b) returns the cross-correlation of matrices a and b with no scaling. xcorr2 is the two-dimensional version of xcorr. example c = xcorr2(a) is the autocorrelation matrix of in...
I have two different normalised atmospheric time series data. Their temporal variation shows a mixed pattern of correlation and anti correlation at different time periods. Aparently there are some lags in these correlations. But when I carry out cross correlation, the plot shows max co...
The 'coeff' option only produces a value of 1 or -1 if a given time shift (lag) results in a perfect positive or negative correlation of two series.For

the value used in the circular shift--note that it's the 233rd position in the overall correlation vector or the -767th lag; this indicates the shift of the second relative to the first is negative. If had shifted t'other way, would have gotten same values shif...
