Class HouseholderHermitian

java.lang.Object

org.ojalgo.matrix.store.operation.MatrixOperation

org.ojalgo.matrix.store.operation.HouseholderHermitian

public final class HouseholderHermitian
extends MatrixOperation

Performs Householder transformation from both sides simultaneously assuming that [A] is hermitian (square symmetric) [A] = [A]^H. Will only read from and write to the lower/left triangular part of [A].

Method Detail

invoke

public static void invoke(double[] data,
                          Householder.Primitive householder,
                          double[] worker)

invoke

public static <N extends Number & Scalar<N>> void invoke(N[] data,
                                                         Householder.Generic<N> householder,
                                                         N[] worker,
                                                         Scalar.Factory<N> scalar)

tred2j

public static void tred2j(double[] data,
                          double[] d,
                          double[] e,
                          boolean yesvecs)

Ursprung JAMA men refactored till ojAlgos egna strukturer

tred2nr

public static void tred2nr(double[] data,
                           double[] d,
                           double[] e,
                           boolean yesvecs)

Ursprung Numerical Recipies. Samma som tred2j, men är inte lika snabb.
