All Implemented Interfaces:

java.io.Serializable

public class RangeCount
extends Histogram

This is the range count implementation. It is based on ISO 45667/4.5

original text:
Das Spannenverfahren
Als Spannen werden die Defferenznen zwischen zwei benachbarten Extremwerten der Schwingung bezeichnet. Die Spannen zwischen einem Minimum (Talwert) und einem Maximum (Gipfelwert) werden positiv, diejenigen zwischen einem Gipfel und dem nachfolgenden Talwert negativ gezählt. Eine Hysterese, die es ermöglicht, kleine Schwinungen auszuklammern, kann vorgesehen werden. Die Hysterese verringert die Anzahl der Spannen und vergrössert ihre Beträge. Deshalb sollten nur kleine Spannen durch Hysterese unterdrückt werden.

RangeCount

public RangeCount()

RangeCount

public RangeCount(double[] values,
          double min,
          double max)

Build the rainflow obejct using double values.

Parameters:

values - the value.

min - the minimum of the values, if maximum and minimum is equal the method will determine it again.

max - the maximum of the values, if maximum and minimum is equal the method will determine it again.

RangeCount

public RangeCount(float[] values,
          double min,
          double max)

Build the rainflow obejct using float values.

Parameters:

values - the value.

min - the minimum of the values, if maximum and minimum is equal the method will determine it again.

max - the maximum of the values, if maximum and minimum is equal the method will determine it again.

RangeCount

public RangeCount(long[] values,
          double min,
          double max)

Build the rainflow obejct using long values.

Parameters:

values - the value.

min - the minimum of the values, if maximum and minimum is equal the method will determine it again.

max - the maximum of the values, if maximum and minimum is equal the method will determine it again.

RangeCount

public RangeCount(int[] values,
          double min,
          double max)

Build the rainflow obejct using int values.

Parameters:

min - the minimum of the values, if maximum and minimum is equal the method will determine it again.

max - the maximum of the values, if maximum and minimum is equal the method will determine it again.

RangeCount

public RangeCount(short[] values,
          double min,
          double max)

Build the rainflow obejct using short values.

Parameters:
