Symmetric Eigenvalue Problem
显示 更早的评论
How do you calculate the symmetric eigenvalue problem in Matlab? I tried using the eig(A) and interestingly enough i get the right numbers but the signs are wrong on some of the numbers. I'm not sure what the difference really is. I was wondering if anyone had any ideas on why this might be happening. Thanks for your help!

"eig" is definitely the correct function, and I think you can rest assured that the output is correct. Can you post a simple example that you think is wrong?

Kenneth, are *all* of the signs reversed? I skimmed a posting recently that indicated there are two different ways to write the eigenvalue problem, and that the only difference between them was to reverse all of the signs.
