BEZIER SPLINES INTERPOLATION ON STIEFEL AND grassmann manifolds
收藏 引用
Journal of Computational Mathematics 2024年 第6期42卷 1554-1578页
作者: Ines Adouani Chafik Samir Department of Mathematics University of SousseTunisia LIMOS-CNRS University of Clermont AuvergneFrance
We propose a new method for smoothly interpolating a given set of data points on grassmann and Stiefel manifolds using a generalization of the De Casteljau *** that end,we reduce interpolation problem to the classical... 详细信息
