Typedef Documentation

◆ ChebyshevDistance

typedef LMetric<INT_MAX, false> ChebyshevDistance

The L-infinity distance.

Definition at line 117 of file lmetric.hpp.

◆ EuclideanDistance

typedef LMetric<2, true> EuclideanDistance

The Euclidean (L2) distance.

Definition at line 112 of file lmetric.hpp.

◆ ManhattanDistance

typedef LMetric<1, false> ManhattanDistance

The Manhattan (L1) distance.

Definition at line 101 of file lmetric.hpp.

◆ SquaredEuclideanDistance

typedef LMetric<2, false> SquaredEuclideanDistance

The squared Euclidean (L2) distance.

Note that this is not technically a metric! But it can sometimes be used when distances are required.
