An Implicit Method for Numerical Solution of Singular and Stiff Initial Value Problems [PDF]

open access: yesJournal of Computational Engineering, 2013
An implicit method has been presented for solving singular initial value problems. The method is simple and gives more accurate solution than the implicit Euler method as well as the second order implicit Runge-Kutta (RK2) (i.e., implicit midpoint rule) method for some particular singular problems.
