摘要 利用B-网坐标方法,讨论Wang加密三角剖分△W上二元三次样条空间S31(△W)的Hermite插值,证明了插值的适定性,并给出S31(△W)上具有局部支集的基函数. By using technique of Bezier-method, Hermite interpolation schemes are constructed based on cubic splines on Wang's refined triangulations. The existence and the uniqueness of the interpolation are discussed. The interpolant has local support and explicit representation.
