why upon entering :-
SchurDecomposition[{{-5.0, 7.0, 6.0, -3.0}, {2.0, -8.0, 3.0, 9.0}, {7.0,
1.0, 2.0, -7.0}, {3.0, 4.0, 4.0, 4.0}}]
does mathematica return a 'T matrix' that is not upper triangular?
some the eigenvalues are complex, so is it because these eigenvalues reside
along the diagonal of 'T' in 2x2 blocks?
