Abstract
The notion of Q-matrices is quite well understood in the theory of linear complementarity problems. In this article, the author considers three variations of Q-matrices, typically applicable for singular matrices. The main result presents a relationship of these notions (for a Z-matrix) with the nonnegativity of the Moore–Penrose inverse of the matrix concerned.
