Abstract
Macro tool in Excellcan be applied to self-define function for handling the interpolation of the rating curve in the hydrological data.In this paper, a unary three point function process of Lagrange interpolation formula is successfully defined.It, simple and prac-tical, can be directly applied to the observed stage-discharge data of the river cross section.Once it is introduced, its usage and effi-ciency are similar to the built-in functions in Excel.关键词
