Inverse interval matrix: A survey
Jǐŕı Rohn, Raena Farhadsefat · Electronic Journal of Linear Algebra · 2011
Results on the inverse interval matrix, both theoretical and computational, are surveyed.Described are, among others, formulae for the inverse interval matrix, NP-hardness of its computation, various classes of interval matrices for which the inverse can be given explicitly, and closed-form formulae for an enclosure of the inverse.
