TY - JOUR AU - Nhat, L. A. PY - 2018 TI - Using differentiation matrices for pseudospectral method solve Duffing Oscillator JO - Journal of Nonlinear Sciences and Applications SP - 1331--1336 VL - 11 IS - 12 AB - This article presents an approximate numerical solution for nonlinear Duffing Oscillators by pseudospectral (PS) method to compare boundary conditions on the interval [-1, 1]. In the PS method, we have been used differentiation matrix for Chebyshev points to calculate numerical results for nonlinear Duffing Oscillators. The results of the comparison show that this solution had the high degree of accuracy and very small errors. The software used for the calculations in this study was Mathematica V.10.4.
