triqs::det_manip::det_manip::inverse_matrix

#include <triqs/det_manip/det_manip.hpp>

Synopsis

1. det_manip::value_type inverse_matrix (int i, int j) const
2. det_manip::matrix_type inverse_matrix () const

Documentation

1) Returns M^{-1}(i,j)

2) Returns the inverse matrix. Warning : this is slow, since it create a new copy, and reorder the lines/cols
