Grihastha means that which "being in and occupied with home, family" or simply "householder". Home shrines can be as simple or as elaborate as the householder can afford. These methods are named after the American mathematician Alston Scott Householder. Likewise, algorithms using Householder and Givens matrices typically use specialized methods of multiplication and storage. Many algorithms use orthogonal matrices like Householder reflections and Givens rotations for this reason. Note that these are particular cases of a Householder reflection in two and three dimensions. The Householder transformation was used in a 1958 paper by Alston Scott Householder. The producers were Matthew Householder and Bill Roper. The current Speaker is Larry Householder, a Republican from Glenford, Ohio. This procedure costs formula 4 arithmetic operations using a technique based on Householder reduction. In other words, both transformations are of Householder transformation type.
