This file has no dependencies other than the STL includes <algorithm> and
<vector>. Simply copy the file into your own project.

If you are working with 3x3 matrices this may also be interesting:

http://cvs.sourceforge.net/viewcvs.py/cctbx/scitbx/include/scitbx/mat3.h?view=markup

Look for "co_factor_matrix_transposed()" and "inverse()". The mat3.h header
file has lots of dependencies, but you could just copy code fragments.
