摘要：
This paper aims at providing some new iterative methods for finding polar decomposition. It is discussed that how we could construct such methods with global convergence. Error analyses for the methods are given to theoretically show their convergence rates. Eventually, computational aspects on many ill-conditioned matrices are brought forward to reveal the applicability of the proposed numerical schemes.
