Yes, it is easy to move array data back and forth between blitz and
libraries like LAPACK and BLAS.

See http://oonumerics.org/blitz/manual/blitz02.html#l39
for a description of constructing blitz arrays from pre-existing
data.

The array member functions data(), stride(), and shape() let
you go in the other direction (from blitz arrays to LAPACK/BLAS):
