                java.lang.String name)

Method Detail

toMatrix

public float[][] toMatrix()

add

public void add(Feature[] newfeatures)

Add the elements in newfeatures to features.

add

public void add(java.util.Vector<Feature> newfeatures)

Add the elements in newfeatures to features.

subset

public float[][] subset(int[] indices)

Return a MxN float[][] matrix with a subset of the current Q features (each N in length), i.e. only M of the Q features are included. Then transpose the NxM matrix so you end up with M N-dimensional elements.

sample

public Features sample(int[] indices)

Return a new Features with all Feature element arrays containing only the elements in indices.

length

public int length()

toString

public java.lang.String toString(int i)

toVector

public float[] toVector(int i)
