Abstract
The spectral collocation or pseudospectral (PS) methods (Fourier
transform methods) combined with temporal discretization techniques to
numerically compute solutions of some partial differential equations (PDEs). In
this paper, we solve the Korteweg-de Vries (KdV) equation using a Fourier
spectral collocation method to discretize the space variable, leap frog and
classical fourth-order Runge-Kutta scheme (RK4) for time dependence. Also,
Boussinesq equation is solving by a Fourier spectral collocation method to
discretize the space variable, finite difference and classical fourth-order Runge-
Kutta scheme (RK4) for time dependence. Our implementation employs the Fast
Fourier Transform (FFT) algorithm.
