Abstract: In this paper, for certain type of structured {0,1,−1}–matrices, we give a complete description of the inner Bohemian inverses over any population containing the set {0,1,−1}. In addition, when the population is exactly {0,1,−1}, we provide explicit formulas for the number of inner Bohemian inverses of these type of matrices.
