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…
To cast the indices in MATLAB®form, add the size ofH: the elementC(k,l) corresponds toC(k+P,l+Q)in the workspace. For example, consider this 2-D cross-correlation: X = ones(2,3); H = [1 2; 3 4; 5 6];% H is 3 by 2C = xcorr2(X,H) ...
The cross correlation function xcorr in matlab provides the lag between two signals. But, Is there any matlab function that calculates the cross correlation between 2 signals and outputs a sigle value i.e < =1?댓글 수: 0 댓글을 달려면 로그인하십시오....
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...

Normalized cross correlation 归一化互相关系数 Python 最近因为工作的关系需要使用matlab作为数据统计的工具,其中一个关键是使用其自相关函数获得数据的估计。自己只在本科时候马马虎虎地学习了一点matlab,这次仗着有C/C++的基础迅速地过了一遍自己需要的matlab的语法,原来这门语言很像脚本啊,同Python一样都是弱类型的,...
