mean shift clustering

这个文件是关于数学模型的，这个文件对于学习自动控制课程同学是很有用的。(This file is on the mathematical model, the file for the automatic control course students learn is useful.)

说明：  用ar方法估计功率谱，并估计信号频率和峰值(Ar method estimates the power spectrum, and estimate the signal frequency and peak)

这个程序是matlab程序，进行结构有限元分析，非常有用！！！(This program is a matlab program, the structural finite element analysis, very useful!!!)

Alamouti方案是为发射天线数为2的系统提供完全发射分集增益的一种空时分组码方案，介绍Alamouti的一种简单的发射方案，包括编码和译码算法及其性能分析，并使用Matlab仿真了Alamouti方案的两发射一接收的情形．(Space-time code of STBC technical coding schemes,a simple transmit and receive way for 2 transmit antenna 1 receive antenna 。)

matlab 进行频谱分析。时域转换频域进行分析。(matlab frequency analytic)

绘制钢筋混凝土偏心受压（拉）构建的m-n相关曲线(Draw reinforced concrete eccentric compression (pull) the correlation curve constructed mn)

图论程序 可以用MATLAB实现 最短路 (Graph Theory with MATLAB program can realize the most short-circuit)

道格拉斯-普克算法(Douglas–Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(Douglas Peucker algorithm is the curve approximated by a series of points, and reduce the number of points of an algorithm. It has the advantages of translation and rotation invariance, given the curve and the threshold, the sampling results must.)

EMD一维信号分解 ；有注释说明，方便阅读；(EMD-dimensional signal decomposition annotated instructions, easy to read )
