A metric is a nonnegative function describing the distance between neighboring points for a given set.

Metric is a college-level concept that would be first encountered in a topology course.

Prerequisites

Vector Space: A vector space is a set that is closed under finite vector addition and scalar multiplication. The basic example is n-dimensional Euclidean space.
