Implicit schemes find the next time step state by solving a system of algebraic equations involving both current and future states. The is a popular implicit approach for the heat equation. It is unconditionally stable and second-order accurate in both time and space, allowing for much larger time steps at the expense of higher computational costs per step. 5.
