That is, these values $\backslash lambda\_i$ are the complex numbers such that there exists a vector $v\_i$ on which $A$ acts by scalar multiplication: :$Av\_i=\backslash lambda\_i\; v\_i.$ Then the spread of $A$ is the non-negative number :$s(A)\; =\; \backslash max\; \backslash .$ 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「Spread of a matrix」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.
