Ted, would it make sense to port parts of QR in-core row-wise Givens solver out of SSVD to work on any Matrix? I know givens method is advertised as stable but not sure if it is the fastest accepted one. I guess they are all about the same.
If yes, i will need also to port the UpperTriangular matrix to adhere to all the bells and wistles, and also have some sort of RowShift matrix (a much simpler analogue of Pivoted matrix for row-rolled buffers). would that make sense? thanks. -D
