我上机实验时在matlab环境上编写的一个关于滤波器的程序文件。(This is a file about filter builded in matlab.)

this code is used to form the ybus admittance matrix of a power system

说明：  地震数据时频分析与分频处理，需要的带走吧，很不错的(Time-frequency analysis and seismic data processing division, need take it away, it is good)

电动执行机构是连接控制器与执行器(阀门)的部件，从控制出来的是离散信号，经零阶保持器后成为一个方波 信号，值都是阶跃跳动，而阀门的实际工作是有一定的行程时间的，即实际上阀门是不可能实现阶跃跳动的，故此需要一个电动执行器，将控制器的阶跃信号变为连续变化信号，假定阀门的行程时间与阀门开度变化成正比。(Electric Actuator is connected controller and actuator (valve) parts, from the control out of the discrete signal by zero-order cage became a square wave signal, values are step-beating, but the actual work of the valve there is a certain amount of travel time, that is, in fact the valve can not be achieved step beat, and therefore need an electric actuator, the controller of the step change in the signal into a continuous signal, assuming that the valve and the valve travel time changes in direct proportion to the door opening.)

初学SAR者非常有用的matlab源代码。(Beginners are very useful SAR matlab source code.)

基于matlab的对多项式数字预失真和查找表数字预失真的比较(Matlab-based digital predistortion and of polynomial lookup tables digital predistortion comparison)

说明：  VRFT，pID整定的先进算法。matlab程序。该方法的引用文献在说明中提及，可运行检验。(A direct PID tuning method.)

Good file to test for nothing.

说明：  图像分类中的交叉验证方法，比如说，一个训练集集合，为了得到其中参数的较准确值，就可以使用此类算法(Image Classification Based on cross-validation method, for example, a collection of training set, in order to obtain more accurate values of these parameters, you can use these algorithms)
