Abstract: With the singular value decomposition and generalized polar decomposition of matrix,this paper obtained new perturbation bounds for the semi-definite factor of generalized polar decomposition of the matrices with full column rank. The conclusions improved the previous results,and the previous results can be viewed as a special case of the new perturbation bounds.
Key words: singular value decomposition, generalized polar decomposition, semi- definite factor, matrices with full column rank
