WebMatrix representation of a relation. If R is a binary relation between the finite indexed sets X and Y (so R ⊆ X ×Y ), then R can be represented by the logical matrix M whose row and column indices index the elements of X and Y, respectively, such that the entries of M are defined by , = {(,), (,). In order to designate the row and column numbers of the matrix, … Web1 mrt. 2024 · Take a matrix which verifies the involved properties and try to see if you can get something. In my attempts I only came to this conclusion, that for the nilpotent-idempotent case there is only the null matrix and for the involuntary-idempotent case there is only the identity matrix.
