贝塞尔插值及其在数值预报中的应用

本文将贝塞尔插值公式写成中央差分的形式，取其二阶便得到我们通常在数值预报中所使肜的内插公式。其后本文给出了它在二维插值中应用的方法和算法。最后本文分析了贝塞尔插值的特点，并将其同三次样条插值和Ｌａｇｒａｎｇｅ插值作了比较。

BESSEL INTERPOLATION AND ITS APPLICATIONSIN NUMERICAL PREDICTION

Written in central difference format and taken only the second orderof the finite difference presentation,this paper provides a Bessel Interpolation formula.Then shows how to use the formula in two-dimensional interpolation and a corresponding source code as well as some important comments on the usage of the program.As a good end,this paper gives an analysis to the Interpolation and makes a comparison with well-known Lagrange interpolation and spline analogue.
