Douglas-Peucker是曲线拟合和压缩数据的最好方法，本人编辑这个程序方便大家调用，拟合压缩曲线。-Douglas-Peucker curve fitting and the compression of data is the best way, I called you to edit this program to facilitate the fitting compression curve.

Douglas-Peucker algorithm for a 2-dimensional data with example in matlab.

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
