摘要
考虑多元插值问题的插值余项估计问题.针对好误差公式的概念,给出了推广好误差公式的概念,并以三维Cartesian点集为例,利用B样条与差商的关系给出Cartesian点集Lagrange插值误差公式的积分形式.该结果可以推广到d维空间中.
This paper generalized good error formulas and considered Lagrange interpolation for Cartesian point sets.Taking 3-dimension Cartesian point sets for example,we provided the integral form of error formulas for this class of interpolation problem using the relationship between the B-spline and finite difference quotient.The results can be generalized in the d-dimensional Cartesian point sets.
