matlab调用zemax程序，使用matlab可以调用zemax优化后的光路数据，并进行处理运算(matlab call zemax program, using matlab can call after zemax optimize the optical path data processing operations)

本文对一个混合灵敏度的系统进行H无穷控制，平台是matlab，有仿真图像(In this paper, the sensitivity of the system is a hybrid H infinity control, the platform is matlab, there are simulated images)

IEEE 802.16d路径损耗模型属于对数正态阴影路径损耗模型。根据郊区宏蜂窝中发射机和接收机之间的障碍物密度，可以分为三种类型ABC。该代码利用MATLAB仿真了IEEE 802.16d路径损耗模型，并画出了未修正和修正的模型曲线以供对比参考。(IEEE 802.16d path loss models are lognormal shadow path loss model. According density suburban macrocell obstacle between transmitter and receiver can be divided into three types A B C. The code using MATLAB simulation of the IEEE 802.16d path loss model, and draw the uncorrected and corrected model curve for comparative reference.)

This program hides one image into another and then recovers it at the output. You will need to chance only the image path in the source code.

极化敏感阵列主板抗干扰性能分析与测试，体现极化敏感阵列利用极化予信息抗干扰的性能优势(sensitive polar array)

用短时傅立叶变换对信号进行时频分析，并有频谱图随着窗的大小进行的对比。(Using short-time Fourier transform of the signal time-frequency analysis and frequency spectrum as the window size of the contrast.)
