Finite difference methods (FDMs) are stable, of rapid convergence, accurate, and simple to solve partial differential equations (PDEs) [53,54] of 1D systems/problems. By applying FDM, the continuous domain is discretized and the differential terms of the equation are converted into a linear algebraic equation, the so-called finite-difference equation.

The finite difference method relies on discretizing a function on a grid. To use a finite difference method to approximate the solution to a problem, one must first discretize the problem's domain. This is usually done by dividing the domain into a uniform grid (see image to the right).
