Shape control of weighted rational quartic interpolating spline curve
摘要
Abstract
To constrain the interpolating curves to be bounded in the given region is an important problem in curve design. A kind of weighted rational quartic spline interpolation is constructed using the rational quartic spline with linear polynomial denominator and the rational quartic spline based on function values. The interpolation function has a simple and explicit mathematical representation. The sufficient conditions for the interpolating curves to be above, below or between the given broken lines or piecewise quadratic curves are derived.关键词
