Homework Statement
matrix:
1/sqrt(2) i/sqrt(2) 0
-1/sqrt(2) i/sqrt(2) 0
0 0 1
Find eigen values and eigen vectors and determine if it is diagonalizable
Homework Equations
The matrix is unitary because Abar*Atranspose=I (identity matrix)
The Attempt at a Solution
I am having problems solving for the eigenvalues and vectors because of the imaginary numbers. What I get is:
lambda-1/sqrt(2) i/sqrt(2) 0
-1/sqrt(2) lambda- i/sqrt(2) 0
0 0 lambda-1
=(lambda-1/sqrt(2))*(lambda- i/sqrt(2))*(lambda-1)-(i/sqrt(2))*(-1/sqrt(2))*(lambda-1)
I need help getting to the next step.
Thanks!
