template<typename TMetricTree >

TMetricTree* proximity::MakeGenMetricTree	(	Matrix &	matrix,
		index_t	leaf_size,
		ArrayList< index_t > *	old_from_new = NULL,
		ArrayList< index_t > *	new_from_old = NULL
	)			[inline]

Creates a ball tree from data.

EXPERIMENTAL FEATURE.

This requires you to pass in two unitialized ArrayLists which will contain index mappings so you can account for the re-ordering of the matrix. (By unitialized I mean don't call Init on it)

Parameters:

	matrix	data where each column is a point, WHICH WILL BE RE-ORDERED
	leaf_size	the maximum points in a leaf
	old_from_new	pointer to an unitialized arraylist; it will map new indices to original
	new_from_old	pointer to an unitialized arraylist; it will map original indexes to new indices
