本代码是线性代数中的matlab实验，用于自动画取图形(This code is linear algebra matlab experiment, for self-animated take graphics)

本代码用matlab编写Runge-Kutta算法程序，并且用ode45函数的编写代码进行对比分析。(The code is written using Runge-Kutta algorithm matlab program, and were analyzed by writing code ode45 function)

说明：  网上大多数matlab代码跑出来的结果不准确，在原有基础上改了一下，但只能在证据之间不产生冲突情况下使用(Most of the MATLAB codes on the Internet run out of inaccurate results. They have been modified on the original basis, but can only be used in cases where there is no conflict between the evidences.)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )

模糊pid控制 完成位置跟踪 模糊pid控制 完成位置跟踪(fuzzy pid controller)

ALOHA协议程序：计算实际产生的业务量 ，吞吐量，平均延迟(ALOHA protocol procedures: calculation of actual traffic, throughput, average delay)

通信原理中，数字调制系统的2ask调制。(Communication theory, digital modulation system 2ask modulation.)

CDMA下行链路采用Rake接收的BER的matlab仿真程序(none)

车牌识别Matlab程序，可直接运行，识别效果很好(License plate recognition Matlab program can be run directly identify good effect)

从网上学习的一种对三个运动目标跟踪的多目标跟踪算法，采用卡尔曼滤波方法进行预测。效果还不错。(From an e-learning to track moving targets on the three multi-target tracking algorithm using Kalman filtering method to predict. Results were pretty good.)
