Metric
A Nonnegative function 
describing the ``Distance'' between neighboring points for a givenSet. A metric satisfies the Triangle Inequality
and is symmetric, so
A Set possessing a metric is called a Metric Space. When viewed as a Tensor, the metric is calleda Metric Tensor.See also Cayley-Klein-Hilbert Metric, Distance, Fundamental Forms, Hyperbolic Metric, MetricEntropy, Metric Equivalence Problem, Metric Space, Metric Tensor, Part Metric, RiemannianMetric, Ultrametric
