摘要：In this talk, we study some numerical methods for solving inverse singular value problems including Newton-type methods and the Ulm-like method. In particular, an extended Newton-type method suiting for the multiple and/or zero singular values is proposed and a new approach is developed for establishing the convergence results of the proposed method. Moreover, numerical experiments are given to illustrating our theoretical results.
