Constructor Detail

ProjectSammon

public ProjectSammon(Projector projector)

Default sammon projector constructor.

Parameters:

projector -

Method Detail

init

public void init()

Description copied from class: ProjectionMethod

Perform any initialization necessary for a given projection method.

Specified by:

init in class ProjectionMethod

project

public void project()

Description copied from class: ProjectionMethod

Perform operations necessary to project the data. For iterable functions this is just a stub.

Specified by:

project in class ProjectionMethod

iterate

public void iterate()

Description copied from class: IterableProjectionMethod

Iterate, if it is iterable. For non iterable-projectors this is just a stub.

Specified by:

iterate in class IterableProjectionMethod

getEpsilon

public double getEpsilon()

Returns:

the epsilon

setEpsilon

public void setEpsilon(double epsilon)

Parameters:

epsilon - the epsilon to set
