Eigenvectors[m] gives a list of the eigenvectors of the square matrix m.
Eigenvectors finds numerical eigenvectors if m contains approximate real or complex numbers.
Eigenvectors corresponding to degenerate eigenvalues are chosen to be linearly independent.
Eigenvectors are not normalized.
For an matrix, Eigenvectors always returns a list of length . The list contains each of the independent eigenvectors of the matrix, followed if necessary by an appropriate number of vectors of zeros.
Eigenvectors[m, ZeroTest -> test] applies test to determine whether expressions should be assumed to be zero. The default setting is ZeroTest -> Automatic.
