Homework Statement
for 2 matrices, A and B
A=
a 0 0
0 -a 0
0 0 -a
B=
b 0 0
0 0 -ib
0 ib 0
Find three orthonormal vectors which are simultaneous eigenvectors of A and B.
Homework Equations
The Attempt at a Solution
I am very new to matrix math. The first thing that confused me was the use of the term "simultaneous eigenvectors." I looked through a bunch of books without finding it, so I assume the question is asking in general for 3 vectors that are also eigenvectors of the matrices. I understand the term orthonormal (both orthogonal and normalized). I'm kind of stuck on where to start. I tried getting eigenvalues for the matrices but the answers didn't seem to make sense.
Any help would be greatly appreciated.
