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…
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...
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...
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...
