Detailed Description

This class computes the Minkowski distance of a Region.

It is defined as: $\left( \sum_{i} (a_i - b_i)^x \right) ^ {1/x}$ , for a given x.

Parameters

exponent the exponent for this distance (the 'x' in the formula) NB: This class is not implemented at the moment.

virtual

This function computes the distance between the two given points.

It needs to be implemented in each subclass. It takes as optional arguments the number of the segments on which to operate.
