How to create a matrix from this relation

  1. Sep 18, 2011 #1
    Let R be a relation on set A={1,2,3,4}
    R = {(1,1) (1,2) (1,3) (1,4) (2,2) (2,4) (3,3) (3,4) (4,4)}
    Construct a matrix of R

    I don't know how to solve matrix can you tell me how to construct a matrix with this Relation

    I'm not sure of what you want to do with the matrix, but a guess would be

    that you do a matrix M with , rows i, columns j, each labelled 1,2,3,4, and then,

    entry m_ij is 1 if i is related to j, and m_ij =0 otherwise.
