In this paper, numerical methods for the solution of linear singular differential system are analyzed. The numerical solution of initial value problem by means of a corresponding finite difference approach and a possible implementation of the product Drazin inverse by vector is discussed. Examples of index-1 and index-2 DAEs have been studied numerically.
