Householder Transformation
In linear algebra, a Householder transformation (also known as a Householder reflection or elementary reflector) is a linear transformation that describes a reflection about a plane or hyperplane containing the origin. The Householder transformation was used in a 1958 paper by Alston Scott Householder. Its analogue over general inner product spaces is the Householder operator. Definition Transformation The reflection hyperplane can be defined by its ''normal vector'', a unit vector v (a vector with length 1) that is orthogonal to the hyperplane. The reflection of a point x about this hyperplane is the linear transformation: : x - 2\langle x, v\rangle v = x - 2v\left(v^\textsf x\right), where v is given as a column unit vector with Hermitian transpose v^\textsf. Householder matrix The matrix constructed from this transformation can be expressed in terms of an outer product as: : P = I - 2vv^\textsf is known as the Householder matrix, where I is the identity matrix.

Householder (Buddhism)
In English translations of Buddhist texts, householder denotes a variety of terms. Most broadly, it refers to any layperson, and most narrowly, to a wealthy and prestigious familial patriarch. In contemporary Buddhist communities, householder is often used synonymously with '' laity'', or non- monastics. The Buddhist notion of householder is often contrasted with that of wandering ascetics ( pi, : '; Sanskrit: ') and monastics (''bhikkhu'' and '' bhikkhuni''), who would not live (for extended periods) in a normal house and who would pursue freedom from attachments to houses and families. Upāsakas and upāsikās, also called śrāvakas and śrāvikās - are householders and other laypersons who take refuge in the Three Jewels (the Buddha, the teachings and the community) and practice the Five Precepts. In southeast Asian communities, lay disciples also give alms to monks on their daily rounds and observe weekly uposatha days. In Buddhist thought, the cultivation of ethic ...

Household
A household consists of two or more persons who live in the same dwelling. It may be of a single family or another type of person group. The household is the basic unit of analysis in many social, microeconomic and government models, and is important to economics and inheritance. Household models include families, blended families, shared housing, group homes, boarding houses, houses of multiple occupancy (UK), and single room occupancy (US). In feudal societies, the royal household and medieval households of the wealthy included servants and other retainers. Government definitions For statistical purposes in the United Kingdom, a household is defined as "one person or a group of people who have the accommodation as their only or main residence and for a group, either share at least one meal a day or share the living accommodation, that is, a living room or sitting room".
