I want to construct a set of matrices with entry either +1, -1 or 0. How to do this either matrix way or using digraph way, that is, if I consider set of digraphs over n vertices, then how do I make the edges have weights either +1, -1 or 0? 2022-08-21 21:48:48 +0100 received badge ● Scholar (source) 2022-08-21 18:25:10 +0100 commented question How to construct matrix space over the set {+1, -1, 0} ?
