It is also referred to as a triangular factor, and is a triangular matrix and they are used in the Householder transformation. A reflector $Q$ belonging to $\backslash mathcal\; M\_n(\backslash R)$ can be written in the form : $Q\; =\; I\; -auu^T$ where $I$ is the identity matrix for $\backslash mathcal\; M\_n(\backslash R)$, $a$ is a scalar and $u$ belongs to $\backslash mathcal$ . ==LAPACK routines== Here are some of the LAPACK routines that apply to block reflectors * " *larft" forms the triangular vector T of a block reflector H=I-VTVH. * " *larzb" applies a block reflector or its transpose/conjugate transpose as returned by " *tzrzf" to a general matrix. * " *larzt" forms the triangular vector T of a block reflector H=I-VTVH as returned by " *tzrzf". * " *larfb" applies a block reflector or its transpose/conjugate transpose to a general rectangular matrix. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Block reflector」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
