Source sentences:
text: the entries on the main diagonal are all zero (that is, the matrix is a hollow matrix), i.e. x ii = 0 for all 1 ≤ i ≤ N , all the off-diagonal entries are positive ( x ij > 0 if i ≠ j ), (that is, a non-negative matrix), the matrix is a symmetric matrix ( x ij = x ji ), and for any i and j ,
