用matlab实现万年编程，显示年月日当前时间(Years to achieve with matlab programming, displays the current month, day time)

计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)

说明：  超声波数值模拟，通过matlab模拟声场的传播(ultrasonic simulation)

LDPC decoder simulation experiment Simulation, this a process using simulink, simulation diagram as shown in the diagram

Matlab实现的一个简单的RAADAR预警雷达模拟 可直接使用。 (Matlab achieve of a simple RAADAR warning radar simulator used directly.)

此为频谱分析工具箱，如寻找频谱峰值等等功能的源代码(This is the spectral analysis toolbox, such as the search for the peak spectrum function of the source code, etc.)

制作出来的显示界面，有坐标，相关显示波形(Produced the display interface, with coordinates, related to the waveform display)

对识别的指纹进行二值化处理，可以让指纹的纹路更清晰。(On binary fingerprint recognition processing, fingerprint patterns can be more clear.)

非线性动力学研究的入门matlab编写程序 主要有混沌 分岔概念的理解 (Getting matlab programming nonlinear dynamics of chaotic bifurcation of the main conceptual understanding)

(1) 新建一个工程demo2，设计一个类Student，其成员变量包括学号(no)、姓名(name)、性别(sex)、专业(major)、联系方式(phone)和地址(addr)。 (2) 为类Student定义成员函数writeTo，实现从给定文本文件中读取学生数据，接口如下： void writeTo (char filename[ ]) (3) 为类Student定义成员函数readFrom，实现将学生数据保存到给定文本文件，接口如下： void readFrom (char filename[ ]) ((1) Create a new project demo2, design a class Student, whose member variables, including school (no), name (name), gender (sex), specialty (major), contact details (phone) and address (addr). (2) define the Student class member function writeTo, students achieve reading data a given text file, the interface is as follows: void writeTo (char filename []) (3) define the Student class member function readFrom, students will achieve data save to text file given, the interface is as follows: void readFrom (char filename []) )
