  • Abstract

In this paper, we present the use of the orthogonal spline collocation method for the semi-discretization scheme of the one-dimensional coupled nonlinear Schro¨dinger equations. This method uses the Hermite basis functions, by which physical quantities areapproximatedwiththeir valuesand derivativesassociatedwith Gaussian points. The convergence rate with order O(h4+τ2) and the stability of the scheme are proved. Conservation properties are shown in both theory and practice. Extensive numerical experiments are presented to validate the numerical study under consideration.
