Localiser.timeDelayLocalisers

Class Simplex

java.lang.Object

Localiser.timeDelayLocalisers.Simplex

All Implemented Interfaces:

TimeDelayLocaliserModel

public class Simplex
extends java.lang.Object
implements TimeDelayLocaliserModel

Time delay based simplex method for localisation. Note that a lot of the code here has been referenced directly from static MCMC functions. This is because both MCMC and Simplex are based on the forward time delay problem hence are mathematically very similar. Simplex is much faster than MCMC but does not provide a full 3D probability distribution.

Method Detail

runAlgorithm

public void runAlgorithm()

Description copied from interface: TimeDelayLocaliserModel

Runs the localisation algorithm an creates a results. The results are dependednt on the localisation class.

Specified by:

runAlgorithm in interface TimeDelayLocaliserModel

changeSettings

public java.lang.Boolean changeSettings()

Description copied from interface: TimeDelayLocaliserModel

Change any settings in the algorithm.

Specified by:

changeSettings in interface TimeDelayLocaliserModel

Returns:

setTimeDelays

public void setTimeDelays(java.util.ArrayList<java.util.ArrayList<java.lang.Double>> timeDelays)

setTimeDelaysErrors

public void setTimeDelaysErrors(java.util.ArrayList<java.util.ArrayList<java.lang.Double>> timeDelayErrors)

setHydrophonePos

public void setHydrophonePos(java.util.ArrayList<java.util.ArrayList<javax.vecmath.Point3f>> hydrophonePos)

setSampleRate

public void setSampleRate(float sampleRate)

setSoundSpeed

public void setSoundSpeed(double speedOfSound)

getLocation

public double[] getLocation()

getLocationErrors

public double[] getLocationErrors()

getRunTime

public long getRunTime()

getChi2

public double getChi2()

getChi2Function

public Simplex.Chi2 getChi2Function()

stop

public void stop()

Description copied from interface: TimeDelayLocaliserModel

Stop the localiser. For MCMC, which can takes minutes to compute this is important. For other localisers, such as Simplex, this is unimportant and can be left blank.

Specified by:

stop in interface TimeDelayLocaliserModel
