NUMERICAL SOLUTION OF NON-LINEAR LIENARD EQUATION USING HAAR WAVELET METHOD
Poincare Journal of Analysis and ApplicationsSummary: In this article, we propose the Haar wavelet method (HWM) for the numerical solution of linear and non-linear Liénard equations. This method transforms the Liénard equation into a system of algebraic equations using truncated Haar wavelet expansions, which is then solved using Newton's iteration method.
