SIMatrix4.Value

説明

4x4行列の(i,j)番目の値（Double）を設定したり、戻したりします。ここで、iは行を示し、jは列を示します。

| m[0,0] m[0,1] m[0,2] m[0,3] |

| m[1,0] m[1,1] m[1,2] m[1,3] |

| m[2,0] m[2,1] m[2,2] m[2,3] |

| m[3,0] m[3,1] m[3,2] m[3,3] |

ヒント: Value は SIMatrix4 オブジェクトのデフォルトのプロパティなので、括弧を使用するだけで、m(j,i)などのようにプロパティ名を省いてもメソッドを呼び出せます。

C#構文

// get accessor

Double ISIMatrix4.get_Value( Int16 in_nRow, Int16 in_nCol );

// set accessor

ISIMatrix4.set_Value( Int16 in_nRow, Int16 in_nCol, Double pVal );

パラメータ

パラメータ タイプ 説明
i Integer 行のインデックスを指定します。
j Integer 列のインデックスを指定します。
