makeYbusmatrix

说明：  用matlab建立任意桁架模型，计算节点矩阵，约束矩阵等(Using matlab to establish any truss model, compute node matrix, constraint matrix, etc.)

matlab 入门基础知识，数字图像处理系列入门教材系列之一(Basic knowledge of introduction to matlab, digital image processing one of series of introductory textbook series)

说明：  MATLAB7.0从入门到精通(光盘).对MATLAB 7.0进行了比较全面的介绍，同时紧密结合典型的应用专题。(MATLAB7.0 from entry to the master (CD-ROM). MATLAB 7.0 on a more comprehensive introduction, at the same time in close connection with the typical application of the topic.)

用来求解某一函数的梯度，维数可以很大，上万维也可以(Used to solve the gradient of a function, the dimension can be large, on the World Wide Web can also be)

变电站谐波状态估计程序，通过量测两个节点的电压和电流，计算得到另一个节点的电压电流相量，两个量测节点相角不同步，以一个节点相角为基准。(Substation harmonic state estimation procedure, by measuring the voltage and current of two nodes, one node is calculated voltage and current phasor, two phase angle measurement nodes are not synchronized with a phase angle of the reference node.)

Frame difference is arguably the simplest form of background subtraction. The current frame is simply subtracted from the previous frame, and if the difference in pixel values for a given pixel is greater than a threshold Ts, the pixel is considered part of the foreground.

说明：  课程中的图像处理实验matlab编程，有助于学习图像处理的初学者(program of matlab image processing , helpful for beginners of image processing)

说明：  各种粒子群优化算法，免疫粒子群优化算法，混沌粒子群算法(Various particle swarm optimization algorithms, immune particle swarm optimization algorithm, chaotic particle swarm optimization algorithm)

该书了详细地介绍了模糊控制理论，同时又给出matlab模糊控制实例(The book describes in detail the theory of fuzzy control, while matlab fuzzy control examples given)

Weighted covariance function. Allows to give more weight on recent observations.
