In numerical analysis, Richardson extrapolation is a sequence acceleration method used to improve the rate of convergence of a sequence of estimates of some value $${\displaystyle A^{\ast }=\lim _{h\to 0}A(h)}$$. In essence, given the value of $${\displaystyle A(h)}$$ for several … Zobacz więcej Notation Let $${\displaystyle A_{0}(h)}$$ be an approximation of $${\displaystyle A^{*}}$$(exact value) that depends on a positive step size h with an error formula of the form Zobacz więcej • Aitken's delta-squared process • Takebe Kenko • Richardson iteration Zobacz więcej • Fundamental Methods of Numerical Extrapolation With Applications, mit.edu • Richardson-Extrapolation • Richardson extrapolation on a website of Robert Israel (University of British Columbia) Zobacz więcej http://www.lifelong-learners.com/pde/com/SYL/s1node17.php
Witryna15 lip 2008 · Unfortunately, Richardson extrapolation does not improve the order of this method. The FOFDM-II is second order uniformly convergent and we show that its order can be improved up to four by using Richardson extrapolation.
