Abstract: Abstract:The positive semi-definite factors of the extended matrix R (A),whose mother matrix is A,and its perburtation matrix R (A)are H and H respectively.By means of singular value decomposition,the perturbation bounds for positive semi-definite factors of extended matrix R (A)are deduced under Frobenius norm.
