Abstract:

The author studied the polar factorization and generalized inverse and perturbation bound of quasirow (column) symmetric matrix, which leads to some new results, and presented the formula of the polar factorization and generalized inverse of quasirow (column) symmetric matrix, which makes calculation easier. In addition, some perturbation bounds of the polar factorization of quasirow (column) symmetric matrix were also presented.
