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。
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...
Compute the cross-correlation on the GPU. Get cc = xcorr2(offsetTemplate,template); Return the result to the MATLAB® workspace using gather. Use the maximum absolute value of the cross-correlation to determine the shift, and compare the result with the known shift. Get cc = gather(cc...
The correlation between the current NASDAQ return and the NYSE return from 20 days before isxcf(1) = -0.0108. The correlation between the NASDAQ and NYSE returns isxcf(21) = 0.7080. The correlation between the NASDAQ return from 20 days ago and the current NYSE return isxcf(41) = 0.0015...
Find the peak in cross-correlation. [ypeak,xpeak] = find(c==max(c(:))); Account for the padding thatnormxcorr2adds. yoffSet = ypeak-size(onion,1); xoffSet = xpeak-size(onion,2); Display the matched area by using thedrawrectanglefunction. The 'Position' name-value pair argument sp...
