Householder-Spiegelungen können zur stabilen Berechnung von QR-Zerlegungen verwendet werden, indem zuerst eine Spalte einer Matrix auf das Vielfache eines Standard-Basisvektors gespiegelt wird; die Transformationsmatrix berechnet und mit der Originalmatrix multipliziert wird. Householder QR Householder transformations are simple orthogonal transformations corre-sponding to re ection through a plane. Re ection across the plane orthogo-nal to a unit normal vector vcan be expressed in matrix form as H= I 2vvT: At the end of last lecture, we drew a picture to show how we could construct a re Ich erkläre die Grundidee der QR-Zerlegung mit Householder-Matrizen und rechne dies an einem konkreten Beispiel ausführlich durch.

Orthonormal transformations Recall that a matrix Qis unitary if QHQ= Ior for real matrices, QTQ= I. For the real case we say that such a matrix is orthonormal. Unitary transformations have the very desirable property of being numerically stable. I've outlined the Householder Reflections method below.
