metric in Swedish

Of or relating to the metric system of measurement.

(analysis) 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 \times 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.
