自相关检测方法是利用信号和噪声在相关域上的差别来构造检测器的。自相关检测是将信号与自身延迟一个时延后的信号作相关处理，或用双通道接收机的输出进行相关，得到扩频信号的自相关函数(Auto-correlation detection method is the use of signal and noise in the relevant field to construct the difference detector. Autocorrelation test is a time delay signal and its delayed signal for correlation, or the output of dual-channel receiver, associated, are spread spectrum signal autocorrelation function)

说明：  改写的matlab fft程序，能对fft结果幅度调整和对横坐标的频率实行自动匹配(Matlab fft procedure adapted to the results of the fft and the abscissa is adjusted automatically to match the frequency of)

SAX比其他符号算法更简便、高效 在符号化过程中实现了减维降噪 ,保证在符号空间计算出的两个符号序列距离满足实际两个时间序列距离的下界要求 ,即不会出现漏报(SAX (Symbolic Aggregate approXimation))

this is also good for learning SVM algorithm

matlab工具箱的rbf网络用于线性回归和曲线拟合，自己手创，绝非复制(matlab toolbox rbf network for linear regression and curve fitting, creating their own hands, not a copy)

基于Matlab的车牌识别系统，采用灰度识别、模块匹配的模式对车牌进行处理(License plate recognition system based on Matlab, using the gray level recognition, module matching mode for processing of license plate)

单相矩阵变换器的经典模型，由整流级和虚拟逆变级组成(The classic model of the single-phase matrix converter, composed by the rectifier stage and virtual inverter stage)

这是一本英文版的书籍，主要讲述模型预测控制，对初学者的学习很有帮助。(This is a book of English version about model predictive control, that is very helpful for beginners learning.)

非常好的matlab的仿真教程，Simulink电路分析应用，有需要的可以看看。(Very good Matlab simulation tutorial, Simulink circuit analysis applications, there is a need to look.)

一杯沸水冷却，圆柱体模型，底面半径0.05m，高0.1m，周围温度20度，初始水温100度 方程是四维输运方程（常数a^2=k/(c*p)，k是热传导系数0.6006焦/（米*秒*度）） 初始条件：t=0时水等于100度 边界条件：1.上下壁都是自由冷却，第三类边界条件，周围温度保持在20度（H=k/h,h取1） 2.杯壁绝热，第二类边界条件 图形显示格式,取过圆柱轴的截面温度变化将其做成动画. (A cup of boiling water for cooling, the cylinder model, the bottom radius of 0.05m, the high-0.1m, an ambient temperature of 20 degrees, the initial water temperature of 100 degrees is four-dimensional transport equation equation (constant a ^ 2 = k/(c* p), k is the thermal conductivity coefficient of 0.6006 J/(m* s* degrees)) initial conditions: t = 0 when the water equivalent to 100 degrees boundary conditions: 1. up and down the wall are free cooling, the third boundary condition, the ambient temperature maintained at 20 degrees (H = k/h, h check one) 2.杯壁insulation, the second boundary condition graphical display format, check-off section of cylindrical shaft temperature change to make animation.)
