The problem with that is that the BLAS is a Fortran library, so expects
Fortran conventions for matrices. The Ada_BLAS bindings are thin, so
don't do the transposition required .

The old GNAT Ada.Numerics.Generic_{Real,Complex}_Arrays did the
transposition explicitly.

There was a discussion about this (and performance aspects) on this
group:
