1. The problem statement, all variables and given/known data
Compute the Eigenvalues and Eigenvectors of A
A= [0 0 1;0 2 0;3 0 0]
2. Relevant equations
where I know the lamdas and plug them into the above equation and expand the system of equations.
3. The attempt at a solution
I have solved for the eigenvalues and got +sqrt(3), -sqrt(3) and 2.
I have solved for the eigenvectors associated with +sqrt(3), -sqrt(3), and checked them in matlab.
For lamda (eigenvalue) of sqrt(3) the eigenvector is
For lamda (eigenvalue) of -sqrt(3) the eigenvector is
But for when the eigenvalue is equal to 2 I come up to problems. where the 2nd row of my matrix is all zeroes. This confuses me because I have checked the vector in matlab and know it should be [0;1;0]. Which is impossible based on the 2nd row being all zeroes.
