WebIn numerical analysis, the Crank–Nicolson method is a finite difference method used for numerically solving the heat equation and similar partial differential equations. It is a second-order method in time. It is implicit in time, can be written as an implicit Runge–Kutta method, and it is numerically stable.The method was developed by John Crank and Phyllis … Web28 mei 2024 · Linearization of a PDE.
