中文说明： matlab实现了五类灰色关联度模型的计算,算法优化非常好，几乎没有循环，主要是基于mtlab的程序，包括广义互相关函数GCC时延估计，处理信号的时频分析，应用小区域方差对比，程序简单。
English Description：
MATLAB implements five model of gray correlation degree computation, algorithm very well, almost no circulation, is based mainly on mtlab programs, including generalized cross correlation function of GCC TDE, time-frequency analysis for signal processing, small regional variance correlation and simple program.
