A Good Approximate Solution for Li´enard Block Pulse Functions

M. H. Heydari, M. R. Hooshmandasl, F. M. Maalek Ghaini


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
