LMS Classical algorithm

用数学的思想编写出的生成均匀分布的1000个随机数，数学思想可参照之前上传的论文(Mathematical ideas to write the generated 1000 uniformly distributed random number,)

在matlab环境下利用句柄图形的方法创建动态图形，绘制了光源动态反射效果示例图形。(In the circumstances the use of matlab handle graphics method to create dynamic graphics, rendering the effect of light reflection sample dynamic graphics.)

This function computes the fourier series of a signal x(t). The amplitudes of the fourier series have the same dimension of the original signal, so this function is useful for immediate computation of the actual frequency components, without further processing.

说明：  月球软着陆仿真：在停泊轨道上，探测器在脉冲制动的作用下，经霍曼变轨，下降到距月面大约 15 公里的近月点，该近月点就是主制动段的初始制动点。主制动段以下是障碍检测与规避和最终着陆段。在主制动段，由于探测器的初始速度很大(1.692km/s)，所以主制动段制导律设计的主要目的就是高效抵消此速度，将探测器导引到期望的末端状态(Lunar soft landing simulation: in the parking orbit, the probe under the action of pulse braking, through the hohmann change of orbit, to descend to about 15 kilometers from the surface of the moon, the near-moon point is the main braking section of the initial braking point. Following is the main braking section for obstacle detection and avoidance and the final landing section. In the main braking section, since the initial velocity of the detector is very large (1.692km/s), the main purpose of the guidance law design of the main braking section is to effectively offset this velocity and guide the detector to the desired terminal state)
