this file computes the distance between two vectors using the dynamic time wrap technique.

采用matlab中的函数对图像进行放大缩小，缩小到原来的0.2倍，再放大到原来大小(Using matlab function image zoom, narrowed to 0.2 times, and then zoom to the original size)

计算水平和竖直放置的平面阵列的方向图，可以通过改变方位角和俯仰角数值仿真图像的改变情况 使用/不使用切比雪夫权值观察图像的变化 提供水平和竖直两个视角观察方向图的形态(the program to simulate pattern of plane array)

FDTD求二维散射，结构为中间长方体，两边为半圆结构(Seeking two-dimensional FDTD scattering, the structure of the middle rectangular, semi-circular structure on both sides of the)

基于burg算法实现的AR模型功率谱计算，算法已经仿真通过，有前向预测误差及后向预测误差，非常适合与学习加深现代谱估计的理论 (Burg algorithm to achieve the AR model power spectrum calculation algorithm has been through simulation, the forward prediction error and prediction error is ideal for learning to deepen modern spectral estimation theory)

关于有限元分析的可以使用的matlab代码，对于FEM编程可以节约不少时间。(Finite element analysis on the matlab code can be used, for FEM programming can save a lot of time.)

说明：  这个模型可以在MATLAB中，为数据库的进入，提供时间倒数，以防止过多地试密码，从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current value of time allowed for a connection to a database to be successful. FIRSTARG, an optional argument, is a string that specifies the JDBC driver to be used establishing the database connection. SECONDARG, an optional argument, is an integer that specifies the length of time the driver will attempt to make a connection to a database. If FIRSTARG is not specified then the default JDBC/ODBC bridge is used to establish the connection to the database. If function is used without arguments then the current time out value is returned. )
