In this presentation the method of least squares will be used to derive a recursive algorithm for automatically adjusting the coefficients of a tapped-delay-line filter, without invoking assumptions on the statistics of the input signals. This procedure, called the recursive least-squares (RLS) algorithm.

原始snake matlab 源碼，簡單版( seg = localized_seg(I,init_mask,max_its,rad,alpha,method) Inputs: I 2D image init_mask Initialization (1 = foreground, 0 = bg) max_its Number of iterations to run segmentation for rad (optional) Localization Radius (in pixels) smaller = more local, bigger = more global alpha (optional) Weight of smoothing term higer = smoother method (optional) selects localized energy 1 = Chan-Vese Energy 2 = Yezzi Energy (usually works better))

通过直接在matlab软件环境下，运行split.m程序，生成结果（图像）(By matlab software environment directly in the running split.m program to generate the results (images) )

说明：  一个完整的OFDM的Matlab仿真程序，建议 Matlab 2014Ra版本上运行(A complete Matlab program for OFDM simulation, the supposed version is Matlab 2014Ra)

说明：  该内容为变压器差动保护的模型搭建图，可以运行，能够进行区内区外故障的仿真实验，并得出正确的结论(transformer protation)
