Open in MATLAB Online I'm not sure I understand your confusion. You start out saying that you have two datasets that differ in magnitude but follow the same pattern, this suggest that if you cross correlate them, it would give you a high normalized cross correlation sequence value at the ...

1. 线性相关(Linear Cross-Correlation)的定义和计算 假设我们手里有两组数据,分别为 个和 个,表示为: 和 , 比 长,即 。序列 和 之间的线性互相关操作表示为 ,其结果也是一个序列,表示为 。具体的操作是用这两个序列进行的一种类似“滑动点积”的操作,如图1和图2所示。
[Using the xcorr method to get the cross correlation] stem(lag, c) [Using stem method to plot the output] This is how our input and output will look like in Matlab command window: Input: Output: As we can see in the OUTPUT, largest spike comes at -8; i.e. when the elements of...
In MATLAB, crosscorrelation could be implemented by modifying and extending Example 2.13, and this has been done in the routine axcor which can be found on this book’s accompanying CD: [rxy,lags]=axcor(x,y); where x and y are the data to be crosscorrelated and rxy is the crosscorre...
