public class DenseVector
extends AbstractVector

Basic implementation for vector.

This is a trivial implementation for vector assuming dense logic, local on-heap JVM storage based on double[] array. It is only suitable for data sets where local, non-distributed execution is satisfactory and on-heap JVM storage is enough to keep the entire data set.
