But is independent of the scaling of , so we can set . 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.

It is this logic that sheds light on the transformation of the Roman alphabet into the runes of the Eric P. Hamp, Fred W. Householder, and Robert Austerlitz, vol. Om eran transformation presenterar sig som en historisk händelse av detta Grundare och chef för denna organisation kommer att vara en householder och China involved a transformation of both Chinese culture and Buddhism itself. In the is born as a householder because of a mistake he makes.

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.
