The following inverse spectrum problem for nonnegative matrices is considered: given a set of complex numbers ฯƒ = {ฮป 1 , ฮป 2 , . . . , ฮป n }, find necessary and sufficient conditions for the existence of an n ร— n nonnegative matrix A with spectrum ฯƒ . Our work is motivated by a relevant theoretical
