摘要
1.问题的提出 近年来,多元样条的研究进程表明,从多变量的观点重新认识一元样条的理论是很有必要的.本文运用重心坐标,以近代的B网方法为工具,重新探讨一元分片多项式的结构,进而为研究多元样条提供工具. 假设Q_n(t)是给定的分割:
A new approach to splines, B-net approach, is proposed in order to provide a new pow-erful tool for studying splines in the multivariate case, and to make new algorithms for pie-cewise polynomials. Some recurrences of B-net coefficients are derived, and their propertiesare investigated for B-splines in one dimension.
