Description
I compared a few implementations of LAPACK and nalgebra. Often LAPACK does additional work for handling for exampe overflow or different scales. Would you be interested in having some of those ideas ported to nalgebra? This usually comes with a (potential) performance penalty.
Some examples:
- `norm_squared` vs `DNRM2`
- the QR implemntation vs `DGEQR2`
I could port something if you are interested? I would start with the QR implementation and the subroutines used.
