Our method exactly extracts all non-regular restricted singular values (RSVs) and deflates the triplet into a regular form while maintaining numerical accuracy. This approach ensures that all nonzero RSVs are computed with high relative accuracy, and all zero RSVs are exactly identified. It also exactly determines the dimensions of the associated nullspaces and their intersections.
