Web文档也会说“如果非零，数据点被认为是周期为x[m-1]-x[0]并返回平滑周期样条曲线近似值。不使用y[m-1]和w[m-1]的值。”，这对我来说意味着它将忽略 x 和 y 中的最后一个坐标。如果我添加坐标，我会遇到这个问题：奇怪。可能与版本有关？ Web实际工作中，变量间未必都有线性关系，如服药后血药浓度与时间的关系；疾病疗效与疗程长短的关系；毒物剂量与致死率的关系等常呈曲线关系。曲线拟合（curve fitting）是指选择适当的曲线类型来拟合观测数据，并用拟合的曲线方程分析两变量间的关系。
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve tha… WebCurve and Surface Fitting Based on Moving Least Squares Method - ... 标签是无源的,这意味着他们是从询问机的射频波形接收所有操 .
