I know that one of the possible solutions to this is a zero matrix, but I am actually looking for a non-zero matrix. In mathematics, particularly linear algebra, a zero matrix or null matrix is a matrix all of whose entries are zero. We typically write a zero-sum game by forming a matrix and allowing one player to choose the rows and the other the columns. It also serves as the additive identity of the additive group of m × n {\displaystyle m\times n} matrices, and is denoted by the symbol O {\displaystyle O} or 0 {\displaystyle 0} —followed by subscripts corresponding to the dimension of the matrix as the context sees fit. ...
