چکیده
|
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 coeffi- cients 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).
