此为，计算地震信号频谱的MATLAB程序，效果较好。可以看到不同道数的频谱(This is calculated seismic signal spectrum MATLAB program is better. Can see that the number of different spectrum Road)

说明：  此程序用来实现双相介质中波场的有限差分方法的数值模拟。(This process used to achieve the two-phase media finite difference method for wave field numerical simulation. )

通过matlab来调用fortran和c语言，其中有很多示例，是一本不可多得的外部程序调用的参考书(By matlab to call fortran and c language, there are many examples, is a rare procedure called an external reference)

角度和时延联合估计（JADE）算法MATLAB程序(Angle and time delay estimation (JADE) algorithm combined MATLAB )

用满应力法对结构进行杆件截面优化设计，MATLAB编程语言(With full stress method for structure bars section optimization design, MATLAB programming language)

自适应子空间辨识，通过输入输出数据，计算状态空间方程，建模并预测。(Adaptive subspace identification, through input and output data, calculates the state space equation, modeling and forecasting.)

说明：  过零点检测 识别正弦波的过零点 进行过零点的检测 识别正弦波的过零点(Zero crossing detection to find the zero crossing of sine wave)

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))

说明：  用CA(元胞自动机)判断网络两点之间的连通性(Using CA to determine the connectivity between two nodes of network)
