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.The coefficient matrix is proved symmetric positive definite matrix,and some sufficient condition for diagonally dominance is gived.The equations can be effecttively solved by many ways and the effectiveness of the algorithm is illustrated by numerical experiments.
