Detailed Description

template<class MatrixType, int DIM = -1, class Distance = nanoflann::metric_L2>
struct nanoflann::KDTreeEigenMatrixAdaptor< MatrixType, DIM, Distance >

An L2-metric KD-tree adaptor for working with data directly stored in an Eigen Matrix, without duplicating the data storage. Each row in the matrix represents a point in the state space.

Example of usage:

Eigen::Matrix<num_t,Dynamic,Dynamic>  mat;
// Fill out "mat"...
typedef KDTreeEigenMatrixAdaptor< Eigen::Matrix<num_t,Dynamic,Dynamic> >  my_kd_tree_t;
const int max_leaf = 10;
my_kd_tree_t   mat_index(dimdim, mat, max_leaf );
mat_index.index->buildIndex();
mat_index.index->...

Template Parameters

DIM	If set to >0, it specifies a compile-time fixed dimensionality for the points in the data set, allowing more compiler optimizations.
Distance	The distance metric to use: nanoflann::metric_L1, nanoflann::metric_L2, nanoflann::metric_L2_Simple, etc.
