Member Function Documentation

◆ operator()()

double operator() ( double t )

inline

EmpiricalDistributionFunction(t) gives edf value at time t, linearly interpolated from cummulative bin probabilities.

Parameters

t	time at which edf is to be calculated.

Definition at line 64 of file NNWaveFitTool.h.

      {
        // pTable is sorted by .first
        if (t > m_pTable.back().first) return 1.0;
        if (t < m_pTable[0].first) return 0.0;
        auto it = lower_bound(m_pTable.begin(), m_pTable.end(), std::make_pair(t, 0.0));
        if (it == m_pTable.begin()) return it->second;
        auto it2 = it;
        --it2;
        double result =  it2->second + (it->second - it2->second) * (t - it2->first) / (it->first - it2->first);
        return result;
      }
