NUMERICAL STABILITY; IMPLICIT METHODS
homepage.math.uiowa.edu/~whan/3800.d/S8-4.pdfWith Euler’s method, this region is the set of all complex numbers z = h for which j1 + zj<1 or equivalently, jz ( 1)j<1 This is a circle of radius one in the complex plane, centered at the complex number 1 + 0 i. If a numerical method has no restrictions on in order to have y n!0 as n !1, we say the numerical method is A-stable.
Backward Euler method - Wikipedia
https://en.wikipedia.org/wiki/Backward_Euler_methodIn 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.
CS3220 Lecture Notes: Backward Euler Method
www.cs.cornell.edu › cs3220 › 2009spThe backward Euler method uses almost the same time stepping equation: k = hf(t+ h;x+ k) Backward Euler chooses the step, k, so that the derivative at the new time and position is consistent with k. Doing this requires solving this equation for k, which amounts to a root nding problem if f is nonlinear, but we know how to solve those.
