original | 元の(成分を交換する前の)連立方程式の右辺を表す列ベクトル。 The original column vector before swapping the components, which represents the right hand side of a simultaneous equation. |
pivot | 連立方程式の左辺の係数行列に対して行った行の交換の情報。
行交換後の係数行列の第\(i\)行成分が
もともと存在していた行番号をpivot[i]とする。 Information of the row swappings applied to the coefficient matrix in the left hand side of the simultaneous equation; pivot[i] is defined such that the \(i\)th row after the row swapping was originally located at the pivot[i]th row. |
