Numerical Method for Inverse Laplace Transform with Haar Wavelet Operational Matrix

Malaysian Journal of Fundamental and Applied Sciences, 2014
Wavelets have been applied successfully in signal and image processing. Many attempts have been made in mathematics to use orthogonal wavelet function as numerical computational tool. In this work, an orthogonal wavelet function namely Haar wavelet function is considered. We present a numerical method for inversion of Laplace transform using the method

Numerical method for solving Schrödinger equations using wavelet basis functions

Journal of the Korean Physical Society
Abstract This paper presents a numerical method for solving Schrödinger equations with arbitrary potentials with the adoption of the qunatum diagonalization scheme and basis functions in the discrete wavelet transform. The quantum diagonalization scheme, developed to solve the Hubbard model and so on, is known to allow the diagonalization of a ...

Wavelet-Petrov-Galerkin Method for the Numerical Solution of the KdV Equation

, 2015
The development of numerical techniques for obtaining approximate solutions of partial differential equations has very much increased in the last decades. Among these techniques are the finite element methods and finite difference. Recently, wavelet methods are applied to the numerical solution of partial differential equations, pioneer works in this ...
