不错的svm讲义，对于svm的背景和原理有比较详细的讲解(svm)

牛顿法求解minf(x)=x1^3+x2^3-3(x1+x2)初始点x=(6,4)精度为0.05。可运行出结果，程序清晰，算法明确。(Newton method for solving min f (x) = x1 ^ 3+ x2 ^ 3-3 (x1+ x2) the initial point x = (6,4) accuracy of 0.05.It can run out the results 。 it s program is clear, and it s algorithm is explicit .)

说明：  该方案以车辆主动悬架为控制对象，将遗传算法应用于LQR控制器的设计。利用遗传算法的全局搜索能力，将主动悬架的性能指标作为目标函数记忆和选择矩阵进行优化设计，以提高LQR的定时效率和性能。(This program takes the vehicle active suspension as the controlled object, and the genetic algorithm is applied to the design of the LQR controller. Using the global search ability of the genetic algorithm, the performance index of the active suspension is used as the objective function memory and option matrix to optimize the design, in order to improve the timing efficiency and performance of LQR.)

时间提前程序，讲时间序列统一提前一年，在雨量站资料处理上很有用(Program ahead of time, say one year ahead of time series, uniform, stand in the rain on the useful data processing)

《MATLAB程序设计教程》内含每章节PPT讲解及讲解实例的仿真源码，会给初学者很好的帮助。(" MATLAB Programming Guide" section contains the PPT and explain each simulation source code examples, will give beginners a good help.)

这是一个提取图像的HSV特征的程序，并将特征以一维向量的形式保存在txt文件或mat文件中，可以直接调用m文件执行。(This is an extract images HSV characteristics of the program, and the characteristics of the form of a one-dimensional vector saved in txt file or mat file, you can directly call the m file execution.)

QPSK Modulation Demodulation, BER vs SNR plot

动态电力系统次同步谐振.次同步谐振一是交流输电系统中由串联电容补偿引起的次同步谐振问题，二是由一些电气装置引起的次同步振荡问题。次同步振荡会使轴系产生很大的扭矩，严重情况下可能导致大轴出现裂纹甚至断裂， 或因反复承受较大转矩造成疲劳积累， 使轴系寿命降低。因此，对次同步振荡进行准确的分析和计算， 采取有效的监视、防止和保护措施是非常重要的。程序是对交流线路串补偿电容引起的次同步振荡抑制的编程。(dynamic power system subsynchronous resonance.)
