这是我自己编写的压缩感知图像重构的算法，直接观测原始信号（二维），最后重建(This is your perception image compression algorithm, direct observation review of the original signal, the reconstruction of a two-dimensional ） （ )

说明：  这是SIFT算法在匹配遥感方面的一个应用，实现自动匹配识别功能(This is the SIFT algorithm to match an application of remote sensing, automatic matching recognition)

这是一个包含了滤波和快速傅里叶变换的地震方面频谱分析程序,用C语言编写(It contains a filter and a Fast Fourier Transform spectrum analyzer earthquakes)

语音信号去噪处理，软阈值、硬阈值、折中阈值，包含语音文件，MATLAB2014a完美运行(speech denoising)

说明：  MIMO信道multinomal residual deterministic仿真(MIMO Channel multinomal residual deterministi c Simulation)

gaussian mixture model to detect foreground

四元数的常见函数在matlab上实现，重要有指数函数，幂函数，余函数等(Common function of arity four based on MATLAB, the important index function, power function, complementary function etc.)

本文提出的中值滤波的快速算法的基本思想是：原始数据序列上中值滤波的滑窗在移动过程中，当前窗只要删除其最早的元素，加入窗后的新元素，即成为下一窗的内容。这个只是Matlab里封装的算法代码(In this paper, the median filtering of the fast algorithm for the basic idea is: the original data sequence in the sliding window filtering process in the mobile, the current window as long as the deletion of its first element, adding a new element after the window, that is, the next window content.)

matlab入门到精髓，很好的资料，学习matlab不可缺少的哦。(matlab entry to the essence of good information, learning matlab Oh indispensable.)
