The reverse order law for the weighted least square g-inverse of multiple matrix products
AIMS MATHEMATICS(2023)
摘要
By using the ranks of the generalized Schur complement, the equivalent conditions for reverse order laws of the {1, 3M}- and the {1, 4N}- inverses of the multiple product of matrices are derived.
