GeometricMean Module

Module Contents

template<typename forward_iterator_type>
std::iterator_traits<forward_iterator_type>::value_type tracktable::arithmetic::geometric_mean(forward_iterator_type input_begin, forward_iterator_type input_end)

Calculate the mean for the un-weighted input points

Note

This function requires a ForwardIterator as its argument. A ForwardIterator is one that can be traversed and dereferenced more than once.

Parameters:

  • input_begin – [in] Start point for mean calculation

  • input_end – [in] End point for mean calculation

template<typename point_iterator_type, typename weight_iterator_type>
std::iterator_traits<point_iterator_type>::value_type tracktable::arithmetic::weighted_sum(point_iterator_type point_begin, point_iterator_type point_end, weight_iterator_type weight_begin, weight_iterator_type weight_end)

Weighted sum of points

Note

You are responsible for ensuring that point_iterator_type::value_type is a Tracktable point and that weight_iterator_type::value_type is a scalar. Also, point_iterator_type and weight_iterator_type must both be ForwardIterators.

Parameters:

  • point_begin – [in] Start point for sum calculation

  • point_end – [in] End point for sum calculation

  • weight_begin – [in] Start of the point weights

  • weight_end – [in] End of the point weights
