Hi all,

Dumb question-- I'd like an LQ factorization from GSL's linear algebra
routines.  One can get an LQ by computing a QR on A^T.  Am I correct
in that, as the public APIs stand, there's no way to compute a QR on
A^T without performing an honest-to-god transpose of A's data?

Thanks in advance,
Rhys
