Hello Rooters, Would it be possible to add a function (in the spirit of sigma's like sumv): TArrayD TArrayD::RunningSum() { TArrayD result(fN); Double_t cur_sum = 0; for (Int_t i=0; i<fN; i++) { cur_sum += fArray[i]; result.AddAt(cur_sum,i); } return result; } to TArrayD ? (And for completeness similar functions to the other TArrayXs) ? I didn't test this function, though... Or is there already a similar function ? thanks, André -- ------------------+---------------------------------- Andre Holzner | +41 22 76 76750 Bureau 32 2-C13 | Building 32 CERN | Office 2-C13 CH-1211 Geneve 23 | http://wwweth.cern.ch/~holzner/
