Results should be the same as the convex optimization technique in the &quot;well-defined&quot; entries, though numerical stability is a real concern that I haven&#x27;t looked at yet. Empirically I haven&#x27;t had any issues, but if you have entries in the singular vectors sufficiently close to zero you can definitely imagine some problems. I don&#x27;t think that&#x27;s unique to this approach, either.
