Initial vector and iteration control in the matriy iteration method

CHEN Jian bin Gu Xiang lin AO Hong fei (School of Civil Engineering,Tongji University,Shanghai 200092,China)  
Analysis of structural dynamic characteristics resorts to “eigenproblem” solution of the dynamic matrix.Matrix iteration method is one of the methods to figure out the first eigenvalue and eigenvector of the matrix.In this paper,the selection of initial vactor and the controlling condition of the iterating cycles in the interation calculation on the matrix are discussed.The new calculation method proposed in this paper is simple to use and accurate according to the verification results of example.
