说明：  用matlab开发的一个简单的预测双色球源码(Using matlab to develop a simple prediction Loans Source)

一些高等数学应用方面的小实验，都运行过的，包括积分变换，解微分方程，差值等，适合matlab初学者。(Some applications of higher mathematics a small experiment, run-off, including the integral transform, solution of differential equations, difference, etc., suitable for matlab beginners.)

Addition and subtraction of signals matlab code

matlab中关于卡尔曼滤波的一些常用子函数及工具(One kinds of the Kalman filter can estimate the position of the ball.)

基于障碍物的三维定位chan和tylor wifi定位算法(Wifi three-dimensional chan and talor localization algorithm...)

用matlab编写的找两个输入量之间的主要特征向量,主要方法采用PCA经典算法.(using Matlab prepared for the volume between two input of the main features of Vector, mainly using PCA classical algorithm.)

用matlab编写的程序，实现图像的3*3、7*7、9*9算术均值滤波和几何均值滤波，文档中有matlab源码以及运行结果截图(Programs written with matlab, image 3* 3,7* 7,9* 9 arithmetic mean filter and geometric mean filter, documentation and operating results have matlab source screenshot)

LDA是一种常见的降维算法，这个算法是完整的算法，可以正常运行(LDA is a common method of Dimension reduction)

说明：  单级倒立摆的稳定控制，实际上是一单输入多输出系统的稳定控制。此时系统输入是电机控制电压u，输出是倒立摆竖直方向角度 和旋臂位置 。对方程(2.5)进行变形即得 与u 之间的输入输出方程,很明显,它是一个不稳定的二阶系统(Single inverted pendulum stability control, is actually a single-input multiple-output system stability control. At this point the system is a motor control input voltage u, the output is inverted pendulum angle and vertical position of spiral arms. Of the equation (2.5) for deformation of the gain and input-output equation between u, obviously, it is an unstable second-order system)
