s注入法对故障定位的应用，用其进行故障精确判断(fault location)

Matlab中的Simulink仿真例子，可用于练习各模块的使用及功能(Matlab example)

说明：  基于matlab中的simulink，进行16QAM的仿真搭建。包括了基带信号发生器，串/并模块，模块1，载波调制模块，高斯白噪声信道，模块2，误码率计算器等，能够较好地实现16QAM的调制解调。(Based on the Simulink of MATLAB, the simulation of 16QAM is built. It includes baseband signal generator, serial / parallel module, module 1, carrier modulation module, Gaussian white noise channel, module 2, bit error rate calculator and so on. It can achieve 16QAM modulation and demodulation well.)

一个ＭＡＴＬＡＢ源函数，用来计算插值，可以选择使用线性，三次样条插值，Hermite插值等方法，希望对大家有用。(A MATLAB source function, used to calculate the interpolation, you can choose to use linear, cubic spline interpolation, Hermite interpolation, in the hope that useful.)

说明：  非常详细的OFDM峰均比各种方法比较，带可复制仿真图！(OFDM PAPR very detailed comparison of various methods with simulation graph can be copied!)

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))

点目标得SAR BP算法成像，具体说明见程序~(Point target is imaged by SAR BP algorithm. See the program for details.)
