Rectangular pulse propagation with FDTD Matlab

（1）对选定二阶电路图进行仿真，得到仿真的输入、输出数据； （2）建立二阶系统函数，用模拟的方法求解其响应，并用matlab平台求出响应波形； （3）对数据进行拟合； （4）对拟合的结果进行误差分析 ((1) on the selected second order circuit diagram of the simulation to obtain a simulation of the input and output data (2) the establishment of the second order system function, solving the response by the simulation method, and was determined using matlab platform response waveform data (3) be fitted (4) the results of the fitting error analysis)

说明：  k均值聚类算法（k-means clustering algorithm）是一种迭代求解的聚类分析算法，其步骤是，预将数据分为K组，则随机选取K个对象作为初始的聚类中心，然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。(The k-means clustering algorithm is an iteratively solved clustering algorithm in which the data is pre-divided into K groups, the K objects are randomly selected as the initial clustering center, and then the distance between each object and the seed clustering center is calculated, and each object is assigned to the clustering center closest to it.)

可以计算两端固定的平面梁的挠度，当划分的单元越多时，梁的挠度值逐渐趋于稳定 (Can calculate the plane beam fixed at both ends of the deflection, when the division of the more units for some time, beam deflection gradually stabilized)
