Find eigenvector in matlab
WebEigenvectors 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.
