The function alphaBetaFilter implements a generic algorithm for an alpha-beta filter that is a linear state estimation for position and velocity given an observed data. It acts like a smoothing. Also closely related to Kalman filters and to linear state observers used in control theory. Its principal advantage is that it does not require a detailed system model.

一段Matlab代码，能够实现Matlab绘制的波形在AutoCAD下绘制出来(A Matlab code, Matlab drawn waveform drawing in AutoCAD)

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列 另外该函数用cos(x)项傅里叶级数展开一个多项式( ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04 Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with highest power on the left, expand f(x) as a sum of scalar multiples of Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)

高斯插值，本程序使用matlab开发环境实现了数值方法的高斯插值内容，方便好用，将所需插值数据加入，即可实现高斯插值(Gaussian interpolation, the program uses matlab development environment to achieve a numerical method of Gaussian interpolation content, easy to use, add the required data interpolation, Gaussian interpolation can be realized)

在matlab环境下利用LSB最低有效位算法将一个图片水印隐藏在载体图片中，并对被隐藏那个信息进行提取。(Matlab environment in the use of least significant bit LSB algorithm will be a picture watermark hidden in the picture carrier, and that information has been extracted hidden.)

讲述经验模态分解的应用，对于其原理及消噪功能有很好的介绍(About the application of EMD)
