[SciPy-Dev] Expose Lapack for Cython

[Ian Henriksen]

Hi all, I have put together pxd files that allow direct access from Cython
to the the blas and lapack functions wrapped in scipy.linalg.blas and
scipy.linalg.lapack. The idea is to make these low level functions
available in Cython without the corresponding Python level function call
that is necessary when using the wrappers already in SciPy. They are
currently in my github repository
https://github.com/insertinterestingnamehere/cylinalg. The approach is
based on the gist https://gist.github.com/pv/5437087. I think this would be
a good addition to SciPy since it is really only another interface to the
wrappers that are already there.

Where would be the best place to put this? Also, what sorts of tests should
be included? Any other input is welcome too.

Thanks!
