Abstract | The dominant poles of a transfer function are specific eigenvalues of the state space matrix of the corresponding dynamical system. In this paper, two methods for the computation of the dominant poles of a large scale transfer function are studied: two-sided Rayleigh quotient iteration (RQI) and the dominant pole algorithm (DPA). First, a local convergence analysis of DPA will be given, and the local convergence neighborhoods of the dominant poles will be characterized for both methods. Second, theoretical and numerical results will be presented that indicate that for DPA the basins of attraction of the dominant pole are larger than those for two-sided RQI. The price for the better global convergence is only a few additional iterations, due to the asymptotically quadratic rate of convergence of DPA, against the cubic rate of two-sided RQI. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
