Peaks计算二维光子晶体带隙程序较长用起来还可以(Peaks calculate two-dimensional photonic bandgap program longer can also use them)

一些关于信号处理谱分析的MATLAB代码，对学习频谱分析比较有用(some code for study spectrum_analysis in signal processing are very useful.)

用matlab编写的简单程序，用自适应门限法将图像二值化，门限是通过最大类间方差确定(Simple program using matlab, using adaptive threshold method image binarization threshold is determined by Otsu)

仿真实现调制解调的过程,使用此程序需要MATLAB开发工具(Simulation of the process of modulation and demodulation, using this program requires MATLAB development tools)

satelite modern project

里面包含了怎么找出一个函数的极点，并用spline函数画出sinc函数的包络线，稍加修改可画出其他的函数的包络线(To draw envelope of sinc function. You can modify it to draw other functions envelope)

matlab绘制指南针，能够调整位置，大小和让其旋转一定角度，很实用(Matlab to draw the compass, it can adjust the position, size, and let the rotation Angle, very practical)

说明：  一个基于pluto传输图像的程序，检测图片并通过pluto传输和接受，接受后画出接受文件的频谱密度图像和星座图(A program based on Pluto to transfer image, detect the image, transmit and accept it through Pluto, draw the spectrum density image and constellation map of the received file after receiving it)

说明：  MATLAB编程(第二版)是老师强烈推荐的，这个电子版是找了好久才找到的，很清晰，有目录。(MATLAB Programming (Second Edition) is the teacher strongly recommended that this electronic version is looking for a long time to find, very clear, there are directories.)

matlab图像处理与识别当中分类识别时的数据归一化处理(matlab image processing data classification and recognition among the normalization process when)
