说明：  在matlab环境下利用bp网逼近某青霉素发酵过程。(Bp network approximation using a penicillin fermentation process.)

本程序可用于实现最小均方误差算法 (LMS algorithm)

用Matlab实现现代功率谱估计，主要有Levinson法，Burg法，协方差法及修正协方差法，四种方法的结果放到一起进行比较，有详细的注释(Using Matlab implementation of modern power spectrum estimation, the main has Levinson Law, Burg method covariance method covariance method, and the amendment, four ways to put together the results of comparison, there is a detailed explanatory note)

对于点检测分析和算例,方便大家学习和使用.(For point detection analysis and examples to facilitate them to learn and use.)

对平面波通过结构的仿真，有TE模和TM模两种模式(Plane wave through the structure of the simulation, the TE mode and TM mode in two modes)

图像配准定义为：对从不同传感器、不同时相、不同角度所获得的两幅或多幅图像进行最佳匹配的处理过程.图像配准需要分析各分量图像上的几何畸变，然后采用一种几何变换将图像归化到统一的坐标系统中。在配准过程中，通常取其中的一幅图像作为配准的标准，称之为参考图像；另一幅图像作为配准图像(Image registration algorithm)

说明：  A ROBUST FAST RECURSIVE LEAST SQUARES ADAPTIVE ALGORITHM

不适用matlab自带滤波器函数的fir低通滤波器设计( low-pass filter )

说明：  双音多频(DTMF)信号的MATLAB仿真，已经通过调试 含源码及课设报告(Matlab simulation of DTMF signal has passed debugging, including source code and course design report)

SkewT分布是近年来得到广泛使用的一种参数化分布。区别于传统的正太分布、学生-t分布，SkewT分布除了具有厚伟特征之外，还引入了偏斜特征。该分布对于金融领域的研究与应用具有十分重要的价值。当然，也是一个重要的统计工具。SkewT分布由Bruce E. Hansen(1994)构造，本源码包括SkewT分布的密度函数、累计概率、随机数生成、理论矩。(SkewT distribution has been widely used recently. Different from traditional Normality and Student-t distribution, SkewT parameterizes both tail-thickness and skewness. SkewT is valuable to financial applications and studies, and other statistic tool. SkewT is firstly introduced by Bruce E. Hansen(1994). This package includes M files on the density of SkewT, CDF, random number generator and theoretical moments of SkewT.)
