在这篇论文,我们为孤立给定的 univariate 花键功能的真实的根建议一个算法,它基于 Descarte 符号和 de Casteljau 算法的规则的使用。数字例子说明算法的灵活性和有效性。
In this paper, we propose an algorithm for isolating real roots of a given univariate spline function, which is based on the use of Descartes' rule of signs and de Casteljau algorithm. Numerical examples illustrate the flexibility and effectiveness of the algorithm.
