MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

非常实用的RS编译码程序。原理可以参考Sklar写的《数字通信》。(See "Digital Communications" by Sklar as the reference for this. These MATLAB scripts answer questions 8.3- 8.7, but using similar methods you might by hand. Includes generating Galois Field addition and multiplication tables, evaluation message and error vectors, and decoding)

This file include matlab files to simulate example in "Basics of MATLAB and Beyond - Andrew Knight" e-book, you can use these .m file to improve your knowledge about matlab

分别利用 Lagrange插值法、分段线性插值法与三次样条法进行插值逼近(Respectively, by Lagrange interpolation, piecewise linear interpolation and cubic spline interpolation approximation method)

采用点门限玻尔兹曼机实现对图像的自动特征提取以及特征选择。(Point-wise gated boltzmann machine was adopted to realize automatic feature extraction and feature selection of images.)

DS证据理论用于信息融合。很多学科都可能用到。(construction of the Membership function. Many disciplines may be used, in particular information class students)

To find the contrast of an image locally.
