摘要
将插值曲线约束于给定的区域之内是插值与逼近的一个重要内容.本文讨论了一种带形状参数的线性有理插值样条的区域控制问题.给出将插值曲线约束于给定的折线及抛物线之上、之下或之间的条件.数值实例表明本文给出的条件在曲线设计中是有效的.
To constrain the interpolating curves to be bounded in the given region is an important content in interpolation and approximation. The region control problem of a rational linear interpolating spline with shape parameters and linear denominator is discussed in this paper. The conditions for the interpolating curve to be above, below or between the given broken lines or piecewise parabolic are derived. Experiments show that the conditions given in this paper are effective in curve design.
