摘要
给出了一种对给定平面上的数据点进行保形的最小二乘逼近的算法，并且得到的逼近曲线是光顺的。本文利用拉格朗日乘数法对带约束条件的参数曲线进行了优化设计。
This article presents a method for shape preserving least-squares approximation to the case of planar parametric curves For the convexity and fairness of the curves,we adjust the curves using the least squares method and curvature property of curves under certain conditions.
