Numerical scheme for nonlinear hyperbolic evolution equations is made based on the implicit Runge–Kutta method and the Fourier spectral method. The detail discretization processes are discussed in case of one-dimensional Klein-Gordon equations. In conclusion, a numerical scheme with the third-order accuracy is presented. The order of total calculation cost is equal to O(N log2 N). As benchmark results, the relation between the numerical precision and the discretization unit size is demonstrated.
