Or perhaps it is the idea of "different" that is broken.
If you are doing the same problem, then the eigenvalues
should be equal in the two systems -- up to numerical
error.
If that is true, then the eigenvectors for each distinct
eigenvalue need to span the same space. Thus the
eigenvectors can always have opposite signs, and for
eigenvalues that are multiple the eigenvectors need look
nothing alike.

Subject: [R] function "eigen" AND Minitab
Hi all. I got a question about eigenvector. I've tried input a symmetric
matrix to both R (using eigen function) and minitab, but the result is
really different. Can anyone tell me what's wrong with that?
Thanks.
