      de.jstacs.data.sequences.ArbitraryFloatSequence

All Implemented Interfaces:

Comparable<Sequence<float[]>>

public class ArbitraryFloatSequence
extends Sequence<float[]>

This class is for any continuous or hybrid sequence. In contrast to ArbitrarySequences, the numeric values are represented by floats instead of doubles. This may be useful if either the represented data are known to be only of float precision or if double precision is dispensible for the sake of memory consumption.
