Comparing implicit vs explicit Euler on a mass-spring-damper system. The implicit method is based on the following paper: D. Baraff and A. Witkin, “Large steps in cloth simulation,” in Proceedings of the 25th annual conference on Computer graphics and interactive techniques - SIGGRAPH ’98, 1998, pp. 43–54.

Backward Euler is an implicit method. You should be solving y=y(i)+h*f(x(i+1),y) at some point. I'm not convinced you're doing that. – sigfpe May 30 '10 at 1:20

written by Tutorial45. The Euler method is a numerical method that allows solving differential equations ( ordinary differential equations ). It is an easy method to use when you have a hard time solving a differential equation and are interested in approximating the behavior of the equation in a certain range. Here we will see how you can use the Euler method to solve differential equations in Matlab, and look more at the most important shortcomings of the method. equation with EULER.m or one of the other numerical methods described below, and you wish to compare with an analytical expression for the exact solution, you should modify the ﬁle yE.m as well as f.m. function yE=yE(t) yE=2*ones(size(t))+t-exp(-t); % Exact solution yE % Note the ones() command, creating a vector of ones. The other alternative for this method is called the Implicit Euler Method, here converse to the other method we solve the non-linear equation which arises by formulating the expression in the below-shown way, using numerical root finding methods.

In contrast to the explicit forward method, the backward method is implicit. f = @(t, x) -x The explicit Euler method sets yn = (1 + hλ)n, the implicit Euler method has [QSS] A. Quarteroni, F. Saleri, P. Gervasio, Scientific Comput The implicit Euler method for the solution of a linear ODE of the form. ˙y = Ay , y(0) = y0 , is defined by the iteration yk+1 = yk + hAyk+1 . Write a MAtlAB or OCtAVE 6.1 Euler's Method . MATLAB has an extensive library of functions for solving ordinary differential equations.

Would some be willing to look at my code (I am not a MATLAB guy, but I try to learn) whether my implementation of implicit method is correct. My thoughts: Explicit method (works fine) : Every values of T are calculated by T 1(i) + heat_coefficient((T1(i+1)-2T1(i)+T1(i-1))/dx^2)*dt , except for the first and the last value which are specified by the I.C. and B.C., respectively.
