Abstract
Based on an analysis of a mechanical problem ,a mathematical model f=ATCA xis derived , whose coefficient matrix T= ATCAcontains a tridiagonal matrix with numbers -1 ,2 ,-1 .The decompo-sition obtained by only applying elementary transformation LU ,LDLTon the matrix is simple in form ,in-dicating a good numerical regularity .Further analysis shows that the mechanical system is a stable positive definite system .关键词
