نوع پژوهش	مقاله چاپ‌شده
کلیدواژه‌ها	Interval matrix, interval arithmetics, inverse eigenvalue problem, nonnegative matrices
چکیده	In this paper, for a given set of real interval numbers σ that satisfies in special conditions, we find an interval nonnegative matrix CI such that for each point set δ of given interval spectrum σ, there exists a point matrix C of CI such that δ is its spectrum. For this purpose, we use unit lower triangular matrices and especially try to use binary unit lower triangular matrices. We also study some conditions for existence solution to the problem
