Hi there,

I have a 4 X 4 matrix,

$\displaystyle

A=\left(\begin{array}[color=Black]{cccc}-2 & 0 & 0& 0 \\0 & 1 & 0 & 1 \\0 & 0 & 0 & 0 \\0 & 1 & 0 & 1\end{array}\right)

$

I've found eigenvalues of this matrix to be 2, -2, 0. I have to find the eigenvectors for each eigenvalue. I'm having great trouble in finding the eigenvectors.

Can any one help?

Thank you for your time.
