In this note, we introduce the singular value decomposition Geršgorin set, SV (A), of an N × N complex matrix A, where N ∞. For N finite, the set SV (A) is similar to the standard Geršgorin set, (A), in that it is a union of N closed disks in the complex plane and it contains the spectrum, σ (A), of
