In this paper, a large class of n dimensional orthogonal and biorthognal wavelet filters(lowpass and highpass) are presented in explicit expression. We also cha
This paper is conceed with the numerical solution of delay differential equations(DDEs).We focus on the error behaviour of Runge-Kutta methods for stiff DDEs. W
Superconvergence of the mixed finite element methods for 2-d Maxwell equations isstudied in this paper. Two order of superconvergent factor can be obtained for
A composition method for constructing high order multisymplectic integrators is pre-sented in this paper. The basic idea is to apply composition method to both
This paper presents a new inexact trust region algorithm for solving constrained nonsmooth optimization problems. Under certain conditions, we prove that the al
Based on the work of paper [1], we propose a modified Levenberg-Marquardt algoithmfor solving singular system of nonlinear equations F(x) = 0, where F(x): Rn -
