WebCrank–Nicolson method In numerical analysis, the Crank–Nicolson method is a finite difference method used for numerically solving the heat equation and similar partial differential equations.[1] It is a second-order method in time. It is implicit in time and can be written as an implicit Runge–Kutta method, and it is numerically stable.
