Detailed Description

A 2-dimensional collection of 1-dimensional histograms that have the same axis.

A MatrixOfH contains a set of TH1 histograms; these histograms are (normally) all created by the constructor. The histograms share the same axis binning, and their names and titles are created using two BinningFun objects that at the same time define the number of histograms.

The histogram names will a concatenation of the name given by the user, and the bin names given by the BinningFun objects. The same applies to the title.

A MatrixOfH is a convenient tool to create a large set of histograms at the same time.

Functions exist to add, multiply, and divide sets of histograms. These operations are performed on pairs of corresponding histograms, if possible.
