中文说明：相关分析过程的matlab方法，信号处理中的旋转不变子空间法，仿真图是速度、距离、幅度三维图像，应用小区域方差对比，程序简单，采用加权网络中节点强度和权重都是幂率分布的模型，Matlab实现界面友好。
English Description：
Correlation analysis method of MATLAB, rotation-invariant subspace methods in signal processing, simulation of speed, distance, three-dimensional images, small regional variance comparison is simple and weighted nodes in the network strength and weight is the power law distribution model, Matlab interface friendly.
