I have two matrices for which part of the eigenspectrum of one matrix, very closely resembles the eigenspectrum of another matrix, but the only way I'm (currently) able to verify this is quite inelegant. I am open to any solution, but to present examples here of what I seek, I find it easiest to ...
You can see that I cited this answer from CV: stats.stackexchange.com/a/154730/211119, but I think this one is much better: stats.stackexchange.com/a/205715/211119 (1) because the title is much clearer and more general and more accurate, and (2) because the answer tells us that not only does the sign not matter, but any non-zero scalar (doesn't have to be +1 or -1) works. However the second question was closed, and I was reluctant to post a link to a "closed" question.
