transform

public final void transform(double[] x,
                            double[] y)

Description copied from class: Transformer

Convert a single point where the output vector is supplied.

transform in class Transformer

Parameters:

x - The input vector.

y - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.
