Abstract: By using the relevant properties of matrix factorization and generalized inverse, some calculating formulas of the polar factorization, generalized inverse and perturbation bounds for universal extended matrix were given. The results of numerical examples show that this method can greatly reduce the calculation amount and storage capacity without changing the numerical accuracy.
Key words: universal extended matrix, polar factorization, generalized inverse, perturbation bound
