matlab7.0的ppt教材，教授一些基本且常用的命令，帮助初学者掌握matlab的使用。(matlab7.0 the ppt textbooks, professors, some of the basic and commonly used commands, helping beginners to master the use of matlab.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

经典的MUSIC算法MATLAB程序，对新手很有用(classical music)

说明：  基于3个节点的闭式网络的牛顿拉夫逊迭代法(Newton Ralph Xun Diedefa based on closed network of 3 nodes)

本程序利用均匀三角多项式曲线画出了漂亮的花瓣图形，图形栩栩如生，淡然调参数混的出不同的图形(This procedure using uniform trigonometric polynomial curve draw a beautiful flower graphics, lifelike graphics, indifferent tone parameters of a different mix of graphics)

二维全息谱的绘制程序，学习故障诊断不可不学的matlab程序代码(good matlab code for holo2D)

最优PID控制器资料，包含matlab程序和详细的文档说明。对做pid控制的肯定有帮助( Optimal PID controller matlab program and documentation)

TSP问题是经典的寻优问题 也是人工智能里一个重要的问题 我编写的程序主要是用蚁群算法来解决这个问题。蚁群算法是人工智能里用来寻优的重要算法 由于蚁群算法的优点使得TSP问题能够实现。 (The TSP problem is a classical optimization problem is also an important problem in artificial intelligence programs written in my main is to use ant colony algorithm to solve the problem. Ant colony algorithm is used in artificial intelligence (ai) optimization algorithm is important due to the advantages of ant colony algorithm can achieve the TSP problem.)

in this program the horizon line detection is found out by using canny edge detector and hough transform.

说明：  PSCAD仿真模型，可以用来研究SSO问题。(The PSCAD simulation model can be used to study SSO problems.)
