用动态图显示极化电磁波的状态。将电磁波的极化表示从琼斯矢量，变换为斯托克斯矢量。适用于学习极化雷达的初学者入门。(Aprogram to show polarimetric wave using stactic or dynamic figures.A program to change the polarimetry representation Jones vector to Stokes vector. For the beginer who learn polarimetric radar.)

自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

引入较好的预处理子，加快共轭梯度法的收敛速度(The introduction of better preconditioners, conjugate gradient method to speed up the convergence rate)

用快速傅里叶变换实现图像融合，将一个人脸上的妆融合到另一个人脸上(With fast Fu Liye transform image fusion, a person will face makeup into another face.)
