Abstract: In this paper, a class of extended exponential general linear methods of second stage seventh order is developed. The resulting integrator is based on the variation of constant formula for initial value problems (IVPs) in Ordinary differential equations (ODEs). Stability analysis indicate that the scheme is zero stable as the parasitic root lies in the unit disk. Lastly, numerical experiment shows that the method is accurate, ecient and compete favourably with Butcher and Wright and Calvo and Palencia methods for solving problems for which exponential general linear method is appropriate.
