When I try to diagonalize this matrix in mathematica 5:
Eigensystem[{{-1, 1, 0, 0}, {1, -2, 1, 0}, {0, 1, -2, 0}, {0, 0, 1, 0}}]
I get this ugly mess
\!\({{Root[1 + 6\ #1 + 5\ #1\^2 + #1\^3 &, 1], Root[1 + 6\ #1 +
5\ #1\^2 + #1\^3 &, 2], Root[
1 + 6\ #1 + 5\ #1\^2 + #1\^3 &, 3], 0}, {{\(-1\) - 3\
Root[1 + 6\ #1 + 5\ #1\^2 + #1\^3 &, 1] - Root[1 + 6\ #1 +
etc etc etc
Mathematica 4 gives me the right answer.
How do I get v5 to not spit this out and what does it mean?
