在地震学中,常常需要比较两列波的相似程度(重复地震探测常用),或两列波拟合程度(反演常用)。 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

MATLAB Online で開く Hello there, I am currently trying to perform a normalised cross correlation on an image with a template (i.e. using the normxcorr2 function). The template is to be rotated through a set of angles and the correlation coefficients generated at each rotation are to ...
Therefore, the population analysis and the temporal profile of the cross-correlated activity revealed that the average correlation coefficient was higher in the NovelMap than in the FamMap task, not only after, but also before, IS onset. This difference was enhanced by the IS presentation. ...

This MATLAB function returns the wavelet cross-correlation sequence estimates for the maximal overlap discrete wavelet transform (MODWT) transforms specified in w1 and w2.
This task was performed using the standard MatLab prewhitening filter. Significance of similarity measures and network trimming The correlation coefficients between the variables form a correlation matrix that represents a weighted network. However, to detect only significant interactions and to trim the ...
