利用Matlab进行柴油机电子调速器，采用模糊控制理论(Using Matlab, electronic engine governor, the fuzzy control theory)

时间序列分析，采用了最小二乘（LS）与自回归(AR)的组合模型，并用MATLAB将其实现(Time series analysis, using a least-squares (LS) and autoregressive (AR) model combination and its implementation using MATLAB)

本程序是用cvx工具箱解决mpc问题的一个简单例子，对于学习cvx的同学大有帮助，cvx效率比较高，是做优化的好工具(This program is a simple example of the problem solved by cvx toolbox mpc, for students to learn cvx great help, cvx more efficient, is a good tool to do optimization)

说明：  gsm的物理层仿真实现，仿真的目的不仅仅在于检查DSP程序实现的错误与否，还通过MATLAB制作相应的码表(gsm realize the physical layer simulation, the purpose of simulation is not merely to check the DSP program realize the error or not, through the production of the corresponding MATLAB code table)

通信中的QPSK相位调制建摸，其中考虑了多径和高斯的影响(Communication QPSK modulation phase modeling, which takes into account the multi-path effects and Gaussian)

阶跃信号与正弦信号调制，在同一张图纸上绘制四个子图。这是一个很基础的编程应用。(Step signal with a sinusoidal signal modulation, drawn with a drawing on four subgraphs. This is a very basic programming application.)

扩展卡尔曼与粒子滤波结合的程序,用扩展卡尔曼作为提议分布，然后利用粒子滤波进行滤波跟踪，效果比常用的粒子滤波要好！均方根误差也比较小。(Extended Kalman particle filter in conjunction with a program, as proposed by the extended Kalman distribution and particle filter for filtering track, the effect is better than the commonly used particle filter! RMS error is relatively small.)

二维空间中的多边形逼近。确定三个顶点a，b，c并且其函数值按从小到大排列。将二维空间中的多边形三个顶点的函数值按从小到大顺序排列， 判断三点或三点函数值的距离是否小于给定阈值.若小于阈值停止循环，得最优解x0=a(Two-dimensional space polygon approximation. Determine the three vertices a, b, c and its function value in ascending order. The three-dimensional space polygon vertices function values ​ ​ in ascending order, function to determine the three o' clock or three values ​ ​ of the distance is less than a given threshold and if less than the threshold value to stop loop, get the best solution x0 = a)
