A Good Approximate Solution for Li´enard Block Pulse Functions

Abstract

In this paper, the Block pulse functions (BPFs) and their

operational matrices of integration and differentiation are used to solve

Li´enard equation in a large interval. This method converts the equation

to a system of nonlinear algebraic equations whose solution is the coefficients

of Block pulse expansion of the solution of the Li´enard equation.

Moreover, this method is examined by comparing the results with the

results obtained by the Adomian decomposition method (ADM) and

the Variational iteration method (VIM
