Abstract
Rationalized Haar functions are developed to approximate the solution of th e differential equations. Properties of rationalized Haar functions are fir st presented, the operational matrix of integration together with product o perational matrix are utilized to reduce the computation of differential eq uations into algebraic equations. The method is computationally attractive, and applications are demonstrated through illustrative examples. (C) 2001 IMACS. Published by Elsevier Science B.V. All rights reserved.
