Ett annat sätt att utföra en ortogonalisering är att använda Householder–transformationer (denna metod utnyttjas i MATLAB-rutinen qr). De baserar sig

What we have discovered in this first video is how to construct a Householder transformation, also referred to as a reflector, since it acts like a mirroring with respect to the subspace orthogonal to the vector $u \text{,}$ as illustrated in Figure 3.3.2.1.

Alston Scott Householder was a real genius I think. The Householder transformation he invented is a master piece of mathematics The Householder transformation is an orthogonal transformation to eliminate more than one element of a given column in a matrix. 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, … Householder Reﬂectors and Givens Rotations MIT 18.335J / 6.337J Introduction to Numerical Methods Per-Olof Persson September 26, 2006 1 Householder transformation This entry describes the Householder transformation u = H ⁢ v , the most frequently used algorithm for performing QR decomposition . The key object here is the Householder matrix H , a symmetric and orthogonal matrix of the form Householder transformation: This method is robust like the one using Givens rotations, easier to implement, and requires less computation. However, it is less bandwidth e cient and more di cult to parallelize than the latter.

This repository implements the Householder transformation algorithm for calculating orthogonal matrices and Stiefel frames. The algorithm is implemented as a Python package with differentiable bindings to PyTorch. In particular, the package provides an enhanced drop-in replacement for the torch.orgqr function. Householder-transformatie In de lineaire algebra is een householdertransformatie een reflectie (spiegeling) in de euclidische ruimte ten opzichte van een hypervlak dat door de oorsprong gaat. Het spiegelvlak wordt bepaald door een normaalvector u van lengte 1 (een eenheidsvector).

Comment. 13 Apr 2017 As we saw earlier, unlike the Gram-Schmidt procedure, the Householder reflection approach does not explicitly form the [latex]Q[/latex] matrix. 9 Jan 2006 The resulting matrix B contains in the upper triangle the matrix R and in each column the necessary information for the Householder vector v of 3 trial videos available.
