查询词典 spline function

Firstly, we prove that if we select nodes properly, and let the distance between these nodes sufficiently small, cubic polynomial spline can approximate a continuously differentiable function, which with continuous derivatives of second order and discontinuity of the first kind in the derivatives of fourth order, to any desirable accuracy. This result lays a theoretical foundation for representing trajectories by splines and double orthogonal basis.

一是证明了适当选取节点并使节点距充分小时，三次多项式样条可以逼近具有二次连续导数的分段四次连续可微函数到足够的精度，这一结论为用样条和双正交基表示弹道打下了理论基础。

阐述了在计算机上如何利用三次样条函数用数学的方法绘制颗分曲线，并提出小于各粒径级别的沙重百分数的方法。

This is for my use of cubic spline function interpolation method procedures.

详细说明：这是我编的利用三次样条法进行函数插值的程序。

A modified shift method is presented based on cubic spline function and least square method.

最近提出的偏移算法是一种基于光线折射和希尔伯特变换的水槽波浪测量方法。

This is a cubic spline interpolation function of the realization of the C code.

详细说明：这是一个三次样条插值函数实现的C代码。

A new application to parameter estimation in cubic spline function fitting via genetic algorithms is presented.

介绍了遗传算法的一种新应用——三次样条函数拟合中的参数估计问题。

Cubic spline function fitting is a good method in the curve fitting because it is characterized by very good subsection smoothness.

三次样条函数拟合是曲线拟合的一个公认的较好方法，它具有很好的分段光滑性。
