Note that scipy exposes most of lapack, so you could make the call you need
In : scipy.linalg.lapack.get_lapack_funcs?
Base Class: <type 'function'>
String Form: <function get_lapack_funcs at 0x40402c6c>
Definition: scipy.linalg.lapack.get_lapack_funcs(names, arrays=(), debug=0,
Return available LAPACK function objects with names.
arrays are used to determine the optimal prefix of
If force_clapack is True then available Atlas routine
is returned for column major storaged arrays with
rowmajor argument set to False.
