Abstract: The present work is devoted to deriving closed form expressions for the elements of the Moore–Penrose inverse of tridiagonal real skew-symmetric matrices. In the first part of the work we obtain results, concerning matrices of even order. A calculation approach for the generalized inverses of odd order matrices is provided.

Keywords: Moore–Penrose inverse, skew-symmetric matrix, tridiagonal matrix.
