Compute the Jordan Canonical form of $\begin{bmatrix}0 & 1 & 0 & 0\\0 & 0 & 0 & 0 \\0 & 0 & 0 & 1 \\ 0 & 0 & 0 & 0\end{bmatrix}$
I don't know what to do after computing the characteristic polynomial, which i got $x^4$=0. This would give us an eigenvalue of x=0 of multiplicity 4.
Any thoughts/comments on where to go after this? Thanks so much!
