Crank-nicolson implicit method

WebA computational diagram for explicit and implicit methods. From the above formula, we will have an explicit method when f = 1 and a fully method when f = 0. In fact f can be any value between 0 and 1, however a common choice for f is 0.5. This is called the Crank-Nicolson method. = 0.5 + 0.5 WebExplicit and implicit methods are approaches used in numerical analysis for obtaining numerical approximations to the solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. ...
