IMPORTANT: Any complex eigenvectors are stored as pairs of real eigenvectors,
    with the understanding that the corresponding complex eigenvalues indicate the
    use of these eigenvectors as a solution basis with the trig functions.

The full, possibly complex eigenvectors are always available using np.linalg(fp.D)
for a fixedpoint_nD object 'fp'.
