"WebFeb 5, 2015 · Eigenvectors are determined only up to a scaling by a constant multiplier. So for an eigenvector ( 1, 1), the vectors ( 2, 2) and ( 0.5, 0.5) are the same eigenvector. It looks like Matlab chooses to normalize the eigenvectors to unit norm. This normalization is the most commonly used.
