Re: LocMax

Hi Roger,

Looking at the documentation, the index variable should contain the length of the array (i.e. 3 - otherwise the method does not know how long the array is), and the method will return the index of the maximum, so you should do this:

Double_t tpz[3] = {10.0, 20.0, 30.0};
std::cout << "Max at index " << TMath::LocMax(3, tpz) << std::endl;

Regards,
James.
