上传的matlab课件，对初学matlab的人应该有很大的帮助，当初我就是看这个课件深入学习了解matlab的。(From the matlab courseware, matlab for beginners should be very helpful when I watch this courseware is to thoroughly study and understand the matlab.)

code for origenal transformation

a matlab introduction

说明：  图像压缩，主成分分析的应用介绍，很有用啊(Image compression, principal component analysis applications introduced useful)

基于MATLAB开发平台的图像去雾程序代码，可运行，适合去雾算法的研究(Image to fog program code based on MATLAB development platform, can run, is suitable for the study to fog algorithm )

雷达电子对抗中的无源干扰的重要形式之一——箔条干扰(chaff jamming)
