说明：  计算一系列值出现的频数，并作出极坐标图，在地理坡向中很有用(Calculated the frequency range of value occurs, and to make Polar, is useful in geographical aspect)

matlab程序设计教程，分为十四章含有各种信号及图像处理问题(matlab programming tutorial, divided into fourteen chapters contain a variety of signal and image processing problems)

关于BPSK的误码率的MATLAB仿真程序。是在高斯信道（AWGN)下的仿真，能够生成图像形式。(BPSK bit error rate on the MATLAB simulation program. In the Gaussian channel (AWGN) under the simulation, can generate the image forms.)

通过使用平面波发计算光子晶体能带图，这个图是我自己弄的，非常辛苦。但是希望能给从事光学研究的朋友的带来帮助。(Calculating the bandgap of a photonic crystal by using a plane wave gives me a very hard picture of myself. But I hope to help those who engage in optical research.)

本资料给出了‘基于重复控制补偿的PID控制’的matlab仿真程序和相应的simulink仿真，以供大家学习和参考(This information gives matlab program of the PID control based on compensation of repetitive control,and alse gives the corresponding simulink simulation model for all to study .)

说明：  pid控制一个2阶系统，并将运行过程中不同观察值送入相应工作空间。(easy pid control.)

用于混沌开发。混沌方式识别的一个matlab程序。十分好用。可以准确预测数据(a very good software which can make more strong and more popular. more good)

duffing系统各参数变化引起的分岔,如激励频率，线性参数k1，还能计算李亚普洛夫指数(duffing system bifurcation parameter variations)

多元逐步线性回归的matlab程序，里面有交通流数据资料，自己用的，可以用的(Multiple stepwise linear regression of the matlab program, there is a traffic flow data, for my own use, can be used)
