I need to solve an undetermined system of equations
(minimum norm solution), several times, with the same
matrix. As far as I know Lapack does this via LQ
In bindings, only QR factorization currently exists.
1) Does someone have bindings for LQ ?
2) Is there a simple way to solve undetermined system
using QR factorization + some tricks with transposes,
using the existing bindings' functions ?
The matrix A can be pretty big and I would prefer not to
create copy of its transpose explicitly -
is it unavoidable if I use QR ?
