Detailed Description

template<unsigned int NFunc, Double_t Func, unsigned int NFuncParams>
struct hit::details::FuncSum< NFunc, Func, NFuncParams >

A sum of NFunc base functions Func.

Template Parameters

NFunc	the number of base functions in the sum
Func	the base function in the sum
NFuncParams	the number of parameters required by Func

This class provides in its eval member a compiled function suitable to be wrapped into a ROOT's TF1 object. The function is the sum of NFunc base functions. Each base function is expected to use NFuncParams parameters. The first function will use the first set of NFuncParams parameters, the second one the next set of NFuncParams parameters, and so on. If NFunc is 0, the value 0 is always returned.
