New... WebJun 20, 2007 · The stability analysis technique, based on the investigation of the spectral structure of the transition matrix of a finite-difference scheme, is applied and it is demonstrated that depending on the parameters of nonlocal conditions the proposed method can be stable or unstable.

Comparison of Explicit and Implicit Finite Difference Schemes o…
Explicit 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. Explicit methods calculate the state of a system at a later time from the state of the system at the current time, while implicit methods find a solution by solving an equation involving both the current state of the system and the later one… Webdo in the section An explicit method for the 1D diffusion equation, but the time step restrictions soon become much less favorable than for an explicit scheme applied to the wave equation. And of more importance, since the solution \( u \) of the diffusion equation is very smooth and changes slowly, small time contract officers
