室外可见光通信信道建模，直射链路和反射链路建模(Outdoor visible light communication channel modeling, direct link and reflective link modeling)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)

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.)

又一个很好的MATLAB应用范例。是关于MATLAB在upf领域的应用问题。(a very import tings!)
