Hi all,

From corresponding reconstructed and true values I’ve built a TH2D Histogram that illustrates an energy smearing. I’d like to convert the TH2D to a Matrix in order to be able to build the inverted matrix and put it back into a TH2D for further calculations within my analysis.

I have not been able to find examples doing this.

Can someone point me to relevant examples?

Thanks

Francesca
