In the fields of computer vision and image analysis, the Harris-affine region detector belongs to the category of feature detection. Feature detection is a preprocessing step of several algorithms that rely on identifying characteristic points or interest points so to make correspondences between images, recognize textures, categorize objects or build panoramas.

有限元法分析电磁场二维问题,中间是1V，外面是0V(Finite Element Analysis of Electromagnetic two-dimensional problem, the middle is 1V, the outside is 0V)

动态聚类的k均值算法，聚类的经典算法，没有改进，仅供初级选手学习。(Dynamic clustering k-means algorithm, clustering algorithm of the classic, no improvement, only for junior players learning. )

this program for face recognizition

经过调试的svm分类程序，很好用，对初学者很有帮助。(After commissioning of the svm classification procedures, useful, useful for beginners.)

共三个文件，以子函数调用的形式，分别实现了Capon的基本算法以及改进的MVDR算法(Of the three files, subroutine calls in the form of, respectively, to achieve the basic algorithm of Capon and improved MVDR algorithm)

涵盖了多种卡尔曼滤波算法及MATLAB实现（书内附有一些例子的源M文件），作者将多年的工作经验融入此书，使之成为学习卡尔曼滤波的同学一本不可多得的经典参考书。(The book content is very comprehensive, covering a wide range of Kalman filter algorithm and MATLAB implementation of many years of work experience will be integrated into the book, making the students learn a Kalman filter rare classic reference book.)

是数学竞赛的往年考题！！希望对大家有用！！(Mathematics exam in previous years the competition! ! Hope it useful! !)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

一种能够消除三维荧光瑞利散射，而且能对移去区域以内插值的形式引入，从而避免缺失值的出现(The function EEMscat is a function that takes an EEM dataset and removes scattering as well as (optionally) interpolates the removed areas such that there are no missing values introduced. )
