A:=Matrix([[1,1,3],[1,5,1],[3,1,1]]);
                               [1    1    3]
                               [           ]
                          A := [1    5    1]
                               [           ]
                               [3    1    1]

LinearAlgebra:-Eigenvectors(A);

                        [-2]  [-1     1    1]
                        [  ]  [             ]
                        [ 3], [ 0    -1    2]
                        [  ]  [             ]
                        [ 6]  [ 1     1    1]
