|
| The differential correction algorithm is a well-known algorithm for finding a rational approximating function to a function on one discrete or continuous variable. In this work we present a modification of the differential correction algorithm using (quasi-random) Korobov points in order to apply it to functions of two continuous variables. The algorithm is applied to the low-energy ion-scattering (LEIS) collision integrals. The approximation obtained is more accurate and about one order of magnitude faster than other approximations in the literature. | |
