SUMMARY

The discussion focuses on finding the real canonical form of the matrix A = [0 2 1; -2 3 0; 1 0 2] and determining the change of basis matrix P. The eigenvalues identified are 0, 2+i, and 2-i, leading to the real canonical form [0 0 0; 0 2 1; 0 -1 2]. The challenge presented is how to derive the matrix P containing the three eigenvectors corresponding to these eigenvalues.

Homework Statement


Let A= [0 2 1;-2 3 0;1 0 2]
Determine a real canonical form of A and give a change of basis matrix P that brings the matrix into this form.


Homework Equations





The Attempt at a Solution


I found my eigenvalues to be 0, 2+i and 2-i.
So, taking 2+i, I get the real canonical form
[0 0 0; 0 2 1; 0 -1 2].
Now using 2+i how do I find the eigenvalues to find a P that contains the 3 eigenvectors?
