Polar Factorization of Quasi-row (column)Symmetric Matrix
摘要
Abstract
The author considered the polar factorization,generalized inverse and perturbation bound of quasi-row (column)symmetric matrix,analyzed some perturbation bounds of the polar factorization of quasi-row (column ) symmetric matrix, and obtained the calculation formula of the polar factorization and generalized inverse of quasi-row (column)symmetric matrix.The results show that the method can not only reduce the calculated amount and memory space,but also can not reduce the numerical accuracy.关键词
