摘要:
This paper deals with idempotent matrices (i.e.. A(2) = A) and t-potent matrices (i.e., B-t B). When both matrices commute, we derive a list of all complex numbers c(1) and c(2) such that c(1) A + c(2)B is an idempotent matrix. In addition. the real case is also analyzed. (c) 2005 Elsevier Inc.
