<- TKDTreeBinning - A class providing multidimensional binning ->

The class implements multidimensional binning by constructing a TKDTree inner structure from the data which is used as the bins. The bins are retrieved as two double*, one for the minimum bin edges, the other as the maximum bin edges. For one dimension one of these is enough to correctly define the bins. For the multidimensional case both minimum and maximum ones are necessary for the bins to be well defined. The bin edges of d-dimensional data is a d-tet of the bin's thresholds. For example if d=3 the minimum bin edges of bin b is of the form of the following array: {xbmin, ybmin, zbmin}. You also have the possibility to sort the bins by their density.

Details of usage can be found in $ROOTSYS/tutorials/math/kdTreeBinning.C and more information on the embedded TKDTree documentation.

Class's constructor taking the size of the data points, dimension, a data array and the number of bins (default = 100).

It is recommended to have the number of bins as an exact divider of the data size. The data array must be organized with a stride=1 for the points and = N (the dataSize) for the dimension.

Thus data[] = x1,x2,x3,......xN, y1,y2,y3......yN, z1,z2,...........zN,....

Note that the passed dataSize is not the size of the array but is the number of points (N) The size of the array must be at least dataDim*dataSize
