Could you give us some more information: Could you provide the 8x8 matrix
explicitly,
together with your Mathematica code?

Greetings,

What is the difference between the NullSpace (m-xIdentityMatrix) and the
Eigenvector. I have a 8x8 matrix and 8 eigenvalues.The NullSpace for all
Eigenvalues is (), but I get 7 Eigenvectors. Can you help me to
understand the difference or how the Eigenvectors were calculated with
Mathematica.

Thanks,
Birgit
