----------------------+-----------------------------------------------------
When using numpy.linalg.eig to compute the eigenvector/eigenvalue pairs of
a non-symmetric (and non-Hessian) matrix, the errors defined as:
np.linalg.norm(np.dot(a, v[:,i]) - w[i]*v[:,i])
is off by several orders of magnitude (up to 14 orders) compared to when
performing the same calculation in octave.
