#### Metric

(mathematics) A function for the measurement of the "distance" between two points in some metric space: it is a real-valued function d(x,y) between points x and y satisfying the following properties: (1) "non-negativity": $d\left(x,y\right) \ge 0$, (2) "identity of indiscernibles": $d\left(x,y\right) = 0 \mbox\left\{ iff \right\} x=y$, (3) "symmetry": $d\left(x,y\right) = d\left(y,x\right)$, and (4) "triangle inequality": $d\left(x,y\right) \le d\left(x,z\right) + d\left(z,y\right)$.
