WebJul 7, 2024 · For instance, the incidence matrix for the identity relation consists of 1s on the main diagonal, and 0s everywhere else. This is called the identity matrix. If a relation on is both symmetric and antisymmetric, its off-diagonal entries are all zeros, so it is a subset of the identity relation. how do i open an rpmsg file in outlook
