In this paper, we apply different mesh-based and meshless methods for solving matrix system carried out from modelling the rockets stability during the firing. Sloped rocket launch and its stability during the firing is one of the most important kinds of defense instruments. The rockets stability during the firing path especially when they are unguided is very important for firing precision. Two mesh-based schemes as finite difference and B-spline methods and two meshless schemes as radial basis function (RBF) and radial basis functions based on finite difference (RBF-FD) are employed for solving underlying system. Numerical results are presented as tabular forms. They show that computational errors and CPU time for RBF-FD as a meshless method are better than other methods.
