All Implemented Interfaces:

DistanceMetric

public class L1Metric
extends AbstractMetric
implements DistanceMetric

Implements the L1 or city block metric. Though this class could use at.ec3.somtoolbox.layers.metrics.LNMetric, for performance issues this less complex computation should be used.

                throws MetricException

Description copied from interface: DistanceMetric

Calculates the distance between two vectors provided by argument vector1 and vector2. A MetricException is thrown, if the dimensionalities of the two vectors differ.

Specified by:

distance in interface DistanceMetric

Specified by:

distance in class AbstractMetric

Parameters:

vector1 - first vector.

vector2 - second vector.
