Functions
template<typename T >
void	igl::group_sum_matrix (const Eigen::Matrix< int, Eigen::Dynamic, 1 > &G, const int k, Eigen::SparseMatrix< T > &A)
	Builds a matrix A such that A*V computes the sum of vertices in each group specified by G.
template<typename T >
void	igl::group_sum_matrix (const Eigen::Matrix< int, Eigen::Dynamic, 1 > &G, Eigen::SparseMatrix< T > &A)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
