这是一份MATLAB基础课件，由于我也是初学者，这部课件讲的很浅显，但比较适合初学者对MATLAB所有功能的一个初步了解内容包括涵数值数组及其运算， M文件和面向对象编成， 字符串数组， 符号变量， matlab 绘图 及 Simulnk动态仿真。以及两个基本浅显的程序题。此为第 4章。(This is a basic MATLAB courseware, because I am also a beginner, this software is very simple-speaking, but more suitable for beginners of all the features of MATLAB, a preliminary understanding of the content including the Han and its numerical array computing, M documents and for object into string array, variable symbols, matlab graphics and dynamic simulation Simulnk. As well as the two basic procedures for simple questions. This is Chapter 4.)

本程序为标准微粒群算法的画图源码，该源码可以画出各种优化图形，描述优化过程(This procedure as the standard particle swarm algorithm for drawing source, the source can be optimized to draw a variety of graphics, optimization process described)

说明：  利用子空间方法实现盲信道均衡的matlab程序，给大家个参考(Subspace method for blind channel equalization to achieve the matlab program, give us a reference)

用MATLAB对给定信号做短时傅里叶分析 用MATLAB对给定信号做短时傅里叶分析(Using MATLAB for a given signal the short time Fourier analysis Using MATLAB for a given signal the short time Fourier analysis)

改进的微分先行PID控制算法仿真源程序。 适用于输入信号跳变剧烈的场合，避免骤升或骤降时引起的系统震荡。(Improved differential forward PID control algorithm simulation source. Applied to the input signal transitions dramatic occasions, to avoid swells or sags caused when the system oscillation.)

此为模式识别中的Fisher线性判别方法求分类器。进行了男、女错误率和总错误率的统计。 全部程序流程如下： 1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本均值m1和内离散度S1； 2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本均值m2和内离散度S2； 3、求最佳变换向量和阀值点； 4、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M； 5、把最佳变换向量和阀值点、x代入判别方程g（x）； 6、对本判别的错误率进行统计。(This is the pattern recognition method, to calculate the Fisher linear discriminant classifier .Were male , female and total error rate error rate statistics . All program flow is as follows : 1 , read FAMALE.TXT file to height or weight to the array, and find the sample mean m1 x1 and internal dispersion S1 2 , read MALE.TXT file to height or weight to the array, and find the sample mean m2 and x2 within the dispersion S2 3 , for the best transformation vector and the threshold point 4 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M 5 , the best transformation vector and the threshold point , x substituted into the discriminant equation g (x) 6 , determine the error rate of the statistics . )
