All Implemented Interfaces:

LimnBasisFactory

Direct Known Subclasses:

PPHolesFactory

public class GTBasisFactory

extends RecordingFactory

GTBasisFactory is a simple factory that creates random projections. It checks that the new projection is sinugular

Constructor Summary

GTBasisFactory(LimnData l)

Method Summary

boolean	checkBasis(double[][] d, double[][] t)
void	gen_norm_variates(double[][] vars)
void	generateBasis(double[][] b, double[][] t) generates a new target basis t, checking that the target is compatible with the base.
void	init() will reseed the basis generator or reset if reading basis from a file this allows the TourEngine to seek to a specific index in a set tour (littletour or filebasistour), and allows a random tour to reset if something has gone strange.
void	measure(double[][] t)
double[][]	newBasis() seeds a new basis array.
void	seedBasis(double[][] d)

Method Detail

generateBasis

public void generateBasis(double[][] b,
                          double[][] t)

Description copied from interface: LimnBasisFactory

generates a new target basis t, checking that the target is compatible with the base.

measure

public void measure(double[][] t)

init

public void init()

Description copied from interface: LimnBasisFactory

will reseed the basis generator or reset if reading basis from a file this allows the TourEngine to seek to a specific index in a set tour (littletour or filebasistour), and allows a random tour to reset if something has gone strange.

newBasis

public double[][] newBasis()

Description copied from interface: LimnBasisFactory

seeds a new basis array. this is used before the production process begins to make sure that the basis arrays are dimensioned and initialized.

seedBasis

public void seedBasis(double[][] d)

gen_norm_variates

public void gen_norm_variates(double[][] vars)

checkBasis

public boolean checkBasis(double[][] d,
                          double[][] t)
