Title: A CLASS OF ALGORITHMS AND NUMERICAL EXPERIMENTS ABOUT THE NONDIAGONALLY DOMINANT TRIDIAGONAL EQUATIONS
Abstract: In this paper,the nondiagonally dominant tridiagonal equations can be translated into pentadiagonal equations by matrix transformation.Furthermore,the coefficient matrix is proved symmetric positive definite matrix and some sufficient conditions of diagonally dominant is given.The equations can be effectively solved by a variety of methods.In this paper,the effectiveness of the algorithm is illustrated by numerical experiments.
