The Householder, a 1960 novel by Ruth Prawer Jhabvala; basis for the film Householder transformation , an algorithm in numerical linear algebra Grihastha , the second phase of an individual's life in the Hindu ashram system
二、Householder算法. 正如定理2显示的那样,Householder变换的主要用途在于,它能和Guass变换一样,通过选取指定的单位向量,把一个给定向量的若干个分量置为0,Householder算法就是用来寻找满足定理2的H,即对任意一个0≠x∈R n ,找到一个H满足Hx=αe 1 。
The method uses Householder-like transformations, sometimes called hyperbolic Householder transformations, that are accumulated so that most computation Översättnig av householder transformation på ungerska.

in terms of Gauss transformations that serve to introduce zeros into the lower triangle of a matrix. Householder transformations are orthogonal transfor-mations (re ections) that can be used to similar e ect. Re ection across the plane orthogonal to a unit normal vector v can be expressed in matrix form as H = I 2vvT: A Householder transformation of a vector is its reflection withrespect a plane (or hyperplane) through the origin represented by its normal vector of unit length , which can be found as. where is the projection of onto . In general, the projection of onto any vector is. The Householder transformation in numerical linear algebra John Kerl February 3, 2008 Abstract In this paper I define the Householder transformation, then put it to work in several ways: • To illustrate the usefulness of geometry to elegantly derive and prove seemingly algebraic properties of the transform; Householder Transformations A matrix H ∈ Rn,n of the form H := I−uu T, where u ∈ Rn and u u = 2 is called a Householder transformation. I For n = 2 we find H = h 1−u2 1 −u1u2 −u2u1 1−u2 2 i.

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.

The Householder transformation is a reflection about a hyperplane with unit normal vector , as stated earlier.An -by-unitary transformation satisfies =.Taking the determinant (-th power of the geometric mean) and trace (proportional to arithmetic mean) of a unitary matrix reveals that its eigenvalues have unit modulus.This can be seen directly and swiftly:
