数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

说明：  matlab 基于形状的图像检索算法 关于七个不变矩的主要算法 中 主要体现出 输入输出 的步骤！ ！！！！！！(matlab image retrieval algorithm based on the shape of seven invariant moments on the main algorithm is mainly reflected the input and output of the steps! ! ! ! ! ! !)

Rayleigh信道性能分析：包含三个文件，分别计算概率密度函数、累积分布函数和误符号率(Rayleigh channel performance analysis: contains three files, calculate the probability density function, cumulative distribution function and the symbol error rate)

Again it is my program work

这可是有关通信方面的MATLAB非常好的资料，而且很权威，是我们学习的号东西，里面有关通信方面的M文件十分齐全(This is related to communications MATLAB very good information, and are the authority, is something we can learn its inside on the communications papers are full of M)

优化设计中常用的 牛顿法 和二次插值法 应用十分广泛 求解凸函数的极值和极值点问题(Commonly used to optimize the design of the Newton' s law and application of quadratic interpolation method for solving a wide range of convex functions and extreme points of the extremal problem)

说明：  滤波方法的通用，值得大家学习 还可以在此基础上改进(Universal filter, is worth learning can be improved on this basis)

说明：  IBR算法在图像匹配上的应用，我也在学习中(Image matching based on IBR)

根据视频场景计算生成人群密度热度图，统计人流分布(Given the video sequnce, this demo counts the people density and return the heat map.)

利用三角分解法这一算法，根据求得的电力系统节点导纳矩阵，求其相应的阻抗矩阵。本程序为IEEE经典算例009节点的程序，程序中附有解释性说明.稍加修改，可以适用于IEEE算例中任意节点。(Using the triangular decomposition algorithm, according to the obtained power system nodal admittance matrix, find the corresponding impedance matrix. The classic example is the program for the IEEE 009 node program, the program accompanied by an explanatory note. Slightly modified, can be applied to any node in the IEEE study.)
