Abstract: The rapid advances of new computational technology in solution of ordinary differential equation (ODE) boundary value problems (BVPs) have made a number of high-quality general-purpose ODE solvers well available, but various ODE problems arising in scientific and engineering applications are frequently not in the 'standard' forms for these codes to accept. However, many problems can be transformed into such forms by using some simple and novel conversion techniques. In this paper, a number of ODE conversion...
