典型的霍曼变轨算法，简单易懂，有清晰的注释(Hohmann orbit typical algorithm, easy to understand, there is a clear Notes)

说明：  实现线性的电力系统潮流计算，分别为首端电压末端功率和末端电压末端功率，可实现一定精度的迭代计算(Power flow calculation in power system)

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。(The Douglas - puke algorithm (Douglas - Peucker algorithm, also called the lamer - Douglas - puke algorithm, iterative adaptive point algorithm, split and merge algorithm) is an algorithm that approximatively represents a curve as a series of points and reduces the number of points. It has the advantages of translation and rotation invariance. After a given curve and threshold, the sampling result is certain.)

说明：  基于Matlab的PDMA通信系统BLER随SNR的变化仿真(simulation of PDMA communication system)

A、名称：限幅滤波法（又称程序判断滤波法） B、方法： 根据经验判断，确定两次采样允许的最大偏差值（设为A）， 每次检测到新值时判断： 如果本次值与上次值之差<=A，则本次值有效， 如果本次值与上次值之差>A，则本次值无效，放弃本次值，用上次值代替本次值。 C、优点： 能有效克服因偶然因素引起的脉冲干扰。 D、缺点： 无法抑制那种周期性的干扰。 平滑度差。(A. Name: Limited filter method (also known as program judgement filter method) B. Method: Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined. Judge each time a new value is detected: If the difference between the current value and the previous value is <=A, the current value is valid. If the difference between the current value and the previous value is greater than A, then the current value is invalid, abandon the current value and replace the current value with the last value. C. Advantages: It can effectively overcome the impulse interference caused by accidental factors. D. Disadvantages: That periodic interference cannot be suppressed. The smoothness is poor.)
