说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

这是一种折线逼近算法，主要被用来拟合直线。(polygonal Approximation used to fit line segment )

在matlab里面，构造三次样条插值函数s(x)来模拟一只飞鸟外形的上部，根据已知的测试数据。(In matlab inside, construct cubic spline interpolation function s (x) to simulate the shape of the upper part of a bird, according to the known test data.)

广义S变换，用于时频分析，是S的改进形式(Generalized S-transform, used in time-frequency analysis, is an improved form of S)

用MATLAB编写的另一个用于图像灰度处理的小程序，很经典的一个图像灰度处理小程序。(Prepared using MATLAB image processing and another for a small procedure, it is the classic image of a small program to deal with.)

本光盘为《详解MATLAB快速入门与应用》一书的配套光盘，包括以下内容： 1.“sample”文件夹：提供了本书各章范例的源程序。(The CD is " Getting Started with MATLAB Detailed application," a book supporting the CD, including the following:. 1 " sample" folder: each chapter provides examples of the book source.)

对于频率估计有效的研究方法 其中有matlab的原始的程序(Frequency estimation matlab)

LTE 64QaM 实现，matlab算法(development of LTE 64Qam)

多维K-means聚类：空间数据分析中最常用的是聚类分析,而K-MEANS算法是聚类分析中常用的,其主要思想是在给定的聚类数目下对多维(我做的是三维空间点)向量进行聚类(aClus.Center.x=m_vecExtreCenter[i].extrePoint.x; aClus.Center.y=m_vecExtreCenter[i].extrePoint.y;)
