实现对激光自混合干涉的仿真，对各个参数的仿真都可以实现。但性能不是很好。(Laser self-mixing interference simulation, simulation of the various parameters can be achieved. But the performance is not very good.)

这是利用matlab编写关于连接网络电缆的最短路程序，在考虑最短路的同时，还考虑到了网络的稳定性等多种其他因素，使用了模拟退火算法解决这一问题，希望能有所帮助。(This is written on the use of matlab to connect the network cable the shortest program, taking into account the short-circuit, while also taking into account the stability of the network and many other factors, the use of simulated annealing algorithm to solve this problem, hoping to help.)

explicit FDM for 1_2D_parabolic partial differential equation

该程序主要是比较对信号分别进行希尔伯特变换HT和广义希尔伯特变换GHT所得到瞬时相位的比较，结果证明GHT较HT对信号有较好抗噪特性，同时瞬时相位也可以用来重构信号，但主要起了指示的作用。(We can get instantaneous phase of the signal by HT or GHT，and the results prove that GHT has better noiseproof feature,namely robustness than HT.In the meantime,we could restruct signal using the information of instantaneous phase,but it mainly has good directives roles.)
