This article presents a method for shape preserving least squares approximation to the case of planar parametric curves For the convexity and fairness of curves, we adjust the curves using the least squares method and curvature property of curves under certain conditions.
利用拉格朗日乘数法对带有约束条件的参数曲线进行了优化设计,给出了一种对给定的平面上的数据点进行保形的最小二乘逼近的算法,使得到的逼近曲线是光顺的。
during the gaussian approximation of laser beam profile, the least squares fitting method is used as a general core algorithm.
