In linear algebra, the Householder operator is defined as follows. Let be a finite dimensional inner product space with inner product and unit vector . Then is defined by This operator reflects the vector across a plane given by the normal vector . It is also common to choose a non-unit vector , and normalize it directly in the Householder operator's expression (Wikipedia).
