reynolds pressure distribution matlab codes

matlab的安装和下载，有具体的安装目录，可以在window系统上下载安装(matlab installation and download, there is a specific installation directory, you can download and install on the window system)

说明：  function [ret,x0,str,ts,xts]=s1(t,x,u,flag) s1 is the M-file description of the SIMULINK system named s1. The block-diagram can be displayed by typing: s1. SYS=s1(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS. Setting FLAG=1 causes s1 to return state derivatives, FLAG=2 discrete states, FLAG=3 system outputs and FLAG=4 next sample time.

说明：  改程序用于在实验中所测量的振动、噪声、水声以及数值模拟监测所得到的信号，实现信号的低通滤波分析。(The modified program is used to measure the vibration, noise, underwater sound and the signal obtained from the numerical simulation monitoring in the experiment to realize the low-pass filtering analysis of the signal.)

说明：  进行多目标优化，主要是使用了NSGA-2的算法，在代码中进行了必要的标注(In the process of multi-objective optimization, nsga-2 algorithm is mainly used and necessary annotation is made in the code)

该文件是前推回代法程序，只要是解决潮流计算，可以更有效达到预期的效果，希望可以给广大朋友起到一定的帮助。(The document is the forward backward substitution method procedures, so long as to solve the power flow calculation, can be more 有效 desired for Xiao Guo, hope to play some of Ji majority of friends to help.)

电磁场与电磁波第四版的答案，比较详细，有用(Electromagnetic field and wave the fourth edition of the answer, more detailed, useful)

HHT变换的一个程序。。。。。。。。。。。(HHT transform a program. . . . . . . . . . .)

较简单的车牌定位方法,并用matlab实现,该程序得到我老师的好评!(A simpler method of license plate location and use matlab implementation, the program received high praise from my teacher!)
