The following three matrices have their main diagonals indicated by red 1's: :$\backslash begin$ \color & 0 & 0\\ 0 & \color & 0\\ 0 & 0 & \color\end \qquad \begin \color & 0 & 0 & 0 \\ 0 & \color & 0 & 0 \\ 0 & 0 & \color & 0 \end \qquad \begin \color & 0 & 0\\ 0 & \color & 0\\ 0 & 0 & \color\\ 0 & 0 & 0\end The antidiagonal (sometimes counterdiagonal, secondary diagonal, trailing diagonal or minor diagonal) of a dimension $N$ square matrix, $B$, is the collection of entries $B\_$ such that $i\; +\; j\; =\; N\; +\; 1$. That is, it runs from the top right corner to the bottom left corner: :$\backslash begin$ 0 & 0 & \color\\ 0 & \color & 0\\ \color & 0 & 0\end == See also == * Diagonal matrix * Trace * Anti-diagonal 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「Main diagonal」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.
