互相关是信号处理中的基本运算式，长用于地震资料的常规数字处理，应用C++语言实现此算法-Cross-correlation signal processing is the basic expression, long used in conventional digital seismic data processing, application C++ language this algorithm

对两个时间序列的交叉普分析，分析时间序列在不同周期上的相关性-Poor cross two time series analysis, time series analysis on the correlation of different periods

广义互相关法的简单算法实现，与直接互相关法有所比较- Generalized simple algorithm to achieve cross-correlation method, and has a direct correlation method comparison
