where “L” is a differential operator and “f” is a given function. Introduction to Spectral method. See our User Agreement and Privacy Policy. The Ritz-Galerkin method was independently introduced by Walther Ritz (1908) and Boris Galerkin (1915). Finite difference method approximate a function locally using lower order interpolating polynomials. In the Galerkin method we could, in particular, select the basis functions as the exact analytical solutions of Maxwell's equations within each element (Harten, et al, 1997).We will call this technique the exact element (EE) method.In this case the volume integrals within each element equal zero. where “L” is a differential operator and “f” is a given function. The new method is based on a Legendre-Galerkin formulation, but only the Chebyshev-Gauss-Lobatto points are used in the compu- tation. Each of these will be explained below.
