基于拉格朗日分布近似泛函（LDAFs），提出了一种新的配置型方法，用于精确逼近离散网格上的函数及其导数。举例说明使用LDAF求解薛定谔方程和福克-普朗克方程的应用。LDAF是通过结合的概念与拉格朗日插值方案。{版权} {美国物理学会}
Lagrange distributed approximating functionals (LDAFs) are proposed as the basis for a new, collocation-type method for accurately approximating functions and their derivatives both on and off discrete grids. Example applications are presented to illustrate the use of LDAFs for solving the Schr{umlt o}dinger equation and Fokker-Planck equation. LDAFs are constructed by combining the DAF concept with the Lagrange interpolation scheme. {copyright} {ital 1997} {ital The American Physical Society}
