光学非球面的模拟和计算，用于计算非球面的斜率(ASPHERE_DIFF calculates the slope of an aspherical surface at a given height)

说明：  一篇有关人脸识别的文章，是2010年在国外做访问学者时下载的，仅供大家参考(An article on face recognition, in 2010 a visiting scholar in foreign countries when downloaded only for your reference)

用matlab编辑的实现检测两直线交点的源代码，源代码包括两个程序(using Matlab Editor Detection two straight intersection of source code, source code, including two procedures)

基于matlab编写的SQP优化算法，用来求解有约束的非线性规划问题(sequential quadratic programming:Used to solve constrained nonlinear programming problems)

Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96.(Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96.)

fisher线性判别器，方法简单直观，对于多维样本有较好的分类能力(fisherclassifer)

说明：  设计低通IIR滤波器；并将此低通滤波器映射为高通、带通或带阻滤波器。并验证变换后的滤波器是否满足指标。并求输入x(n)=[cos(w1n)+cos(w2n)]u(n)经过系统后的输出y(n)(Low-pass IIR filter design and mapping this low-pass filter high pass, band pass or band stop filter. And verify whether the filter transformation to meet the target. And to seek input x (n) = [cos (w1n)+ cos (w2n)] u (n) through the system output after the y (n))

Three phase 6-pulse semi controlled rectifier simulation using matlab simulink

ILC 迭代学习控制的matlab程序，是学习迭代过程的好资料，这是第二部分，程序运行效果非常好。(Iterative Learning Control ILC matlab program, the iterative process of learning good information, this is the second part of the program runs very good.)

经验模态分解（EMD）方法（平稳化过程）是一种全新的处理非平稳数据序列的方法，其基本思想是：假如一个原始数据序列X(t)的极大值或极小值数目比上跨零点（或下跨零点）的数目多两个（或两个以上），则该数据序列就要进行平稳化处理(Empirical Mode Decomposition (EMD) method (a smooth process) is a new deal with non-stationary data sequence method, the basic idea is: If a raw data sequence X (t) the maximum or minimum number of than the cross-zero (or under the cross-zero) number more than two (or more), then the data is necessary to carry out a smooth sequence of treatment)
