ROOT 6.14/05 Reference Guide |
Class describing the unbinned data sets (just x coordinates values) of any dimensions.
There is the option to construct UnBindata copying the data in (using the DataVector class) or using pointer to external data (DataWrapper) class. In general is found to be more efficient to copy the data. In case of really large data sets for limiting memory consumption then the other option can be used Specialized constructor exists for using external data up to 3 dimensions.
When the data are copying in the number of points can be set later (or re-set) using Initialize and the data are inserted one by one using the Add method. It is mandatory to set the size before using the Add method.
