University of Guilan Journal of Mathematical Modeling 2345-394X 2 1 2014 05 01 Convergence of the multistage variational iteration method for solving a general system of ordinary differential equations 90 106 104 EN Mehdi Bastani Journal Article 2015 05 21 In this paper, the multistage variational iteration method is implemented to solve a general form of the system of first-order differential equations. The convergence of the proposed method is given. To illustrate the proposed method, it is applied to a model for HIV infection of CD4+ T cells and the numerical results are compared with those of a recently proposed method.
