| Abstract: | This paper presents a direct iterative model reducing method on the dynamic system formed in computational structure dynamics and large scale system theory. The operations of this algorithm are very simple and it is not necessary to calculate the eigenpairs of system matrix, so this method relaxes restrictions on the property of system matrix. It has extensive applications and high approximating degree. |
