In numerical analysis and scientific computing, the backward Euler method (or implicit Euler method) is one of the most basic numerical methods for the solution of ordinary differential equations. It is similar to the (standard) Euler method, but differs in that it is an implicit method. The backward Euler method has error of order one in time.

Forward and Backward Euler Methods. Let's denote the time at the nth time-step by t n and the computed solution at the nth time-step by y n, i.e., . The step size h (assumed to be constant for the sake of simplicity) is then given by h = t n - t n-1. Given (t n, y n), the forward Euler method (FE) computes y n+1 as

21.01.2022 · Euler Backward Method. An implicit method for solving an ordinary differential equation that uses in . In the case of a heat equation, for example, this means that a linear system must be solved at each time step. However, unlike the Euler forward method, the backward method is unconditionally stable and so allows large time steps to be taken.

Backward Euler Method. This module illustrates the implicit Backward Euler method for numerically solving initial value problems for ordinary differential equations. A numerical method for an ordinary differential equation (ODE) generates an approximate solution step-by-step in discrete increments across the interval of integration, in effect producing a discrete sample of approximate values of the solution function.

For the Backward Euler method, we must solve ~x i+1 = ~x i +hf~(~x i+1), for ~x i+1 or F~(~x i+1) = ~x i+1 −~x i −hf~(~x i+1) = 0. The Jacobian of F~ is then given by, DF(~x) = I−hDf(~x). Putting all these ideas together we have the following Backward Euler code. function [t,y]=beul(f,df,y0,t0,tf,n) h=(tf-t0)/n; t=linspace(t0,tf,n+1); y=zeros(n+1,length(y0));

The method says to take the slope from the next point, which is the unknown one, which is why this is an implicit method.

The backward Euler method is a numerical integrator that may work for greater time steps than forward Euler, due to its implicit nature. However, because of this, at each time-step, a multidimensional nonlinear equation must be solved. Eq. (16.78) discretized by means of the backward Euler method writes

Nov 01, 2021 · The backward Euler method is an implicit method: the new approximation y n+1 appears on both sides of the equation, and thus the method needs to solve an algebraic equation for the unknown y n+1. Frequently a numerical method like Newton's that we consider in the section must be used to solve for y n+1. The backward Euler method is also a one-step method similar to the forward Euler rule.
