Eigenvectors finds numerical eigenvectors if m contains approximate real or complex numbers.
Eigenvectors corresponding to degenerate eigenvalues are chosen to be linearly independent.
For an nn matrix, Eigenvectors always returns a list of length n. The list contains each of the independent eigenvectors of the matrix, followed if necessary by an appropriate number of vectors of zeros. »
Eigenvectors with numeric eigenvalues are sorted in order of decreasing absolute value of their eigenvalues.
