Why does the random shift in the QR eigenvalue algorithm work in the non-symmetric case over...
Now, if you do it without shifts, it will never converge if two eigenvalues have equal absolute values (which is not such an exceptional case: most real-valued matrices have conjugate pairs, the companion … However, in this case, one can start with small eigenvalues and have quite large below diagonal entries, so at least in the beginning I do not see why it is any better than shifting by a totally random …
