ds algorithm motion estimation

very useful for inverter design in power electronics

PCA:Principal Components Analysis It computes Principal Component Analysis, i.e., the linear transform which makes data uncorrelated and minize the reconstruction error.

最小二乘算法来实现esprit算法，该代码已经在matlab中运行过绝对可以放心使用(Least squares algorithm to achieve esprit algorithm, the code has been run in matlab absolutely safe to use)

周期图法在雷达信号处理、目标检测、以及目标跟踪中有重要作用。他的主要特点为从噪声中将所需要的周期信号的特征以功率谱的形式表征出来，通过设置合适的阈值可以代表目标。调频信号则是典型的脉冲压缩信号，其扩频特性使得其不易受噪声干扰。(Periodogram in radar signal processing, target detection, and target tracking plays an important role. His main characteristics will be required from the noise characteristics of periodic signals in the form of the power spectrum characterized it, by setting the appropriate threshold may represent the target. FM signal is a typical pulse compression signal, the spreading characteristics make it less susceptible to noise interference.)

关于高阶循环累积量的的程序，用于信号调制识别(high order cyclic cumum)

利用wolfe算法，编写了wolfe程序模块。测试数据引用《最优化方法及其Matlab程序设计》(马昌凤编)的Armijo准则搜索例题(Use wolfe algorithm, written wolfe program modules. Test data reference " optimization methods and Matlab programming" (Ma Changfeng ed.) The search criteria examples Armijo)

中心极限定理的验证，三种独立分布具有同样的均值与方差，大量叠加后分布趋于正态(Central limit theorem verification, three kinds of independent distribution has the same mean and variance, a large number of superimposed normal after the distribution tends)

matlab code for graphical calculation in networking area

说明：  无人机路径规划，提出改进的A*算法，参考2019年研究生数学建模竞赛F题(UAV path planning, propose improved a * algorithm, refer to the f problem of 2019 graduate mathematical modeling competition)
