Lagrange 插值,该程序实现线性，二次，三次等等lagrange插值功能。-the interpolation of Lagrange

采取了中值滤波，极大值取点线性插值，一元等距拉格日插值，以及合并滤波等算法将所有的干扰数据滤去-Taken a median filter, with the maximum take-point linear interpolation, one dollar at equidistant Lagrange interpolation, and the combined filtering algorithm will filter out all interference data
