metrices

Noun

metric (plural metrics)

1. A way to measure something; a means of deriving a quantitative measurement or approximation for otherwise qualitative phenomena (especially used in engineering).
   • What metric should be used for performance evaluation?

   Synonyms:

   measure

2. A function which satisfies a particular set of formal conditions, created to generalize the notion of the distance between two points. Formally, a real-valued function d on M×M, where M is a set, is called a metric if (1) d(x,y)=0 if and only if x=y, (2) d(x,y)=d(y,x) for all pairs (x,y), and (3) d obeys the triangle inequality.
   • As we shall see, these metrics are constructed from a Green function.2000, Lutz Habermann, Riemannian Metrics of Constant Mass and Moduli Spaces of Conformal Structures

   Synonyms:

   distance function

3. A metric tensor.
