摘要
In this paper we present two pseudospectral methods based on Fourier series and rational Chebyshev functions for solving the Nagumo equation. In each of the two presented methods the problem is reduced to a system of ordinary differential equations that is solved by the leapfrog difference scheme and the fourth-order Runge-Kutta method, respectively. We compare the numerical solutions with the exact solution to validate the numerical methods. Numerically comparing of the two methods also will be considered.
