Matrix.M12 屬性


取得或設定這個 Matrix 結構之第一列第二行的值。Gets or sets the value of the first row and second column of this Matrix structure.

 property double M12 { double get(); void set(double value); };
public double M12 { get; set; }
member this.M12 : double with get, set
Public Property M12 As Double



這個 Matrix 之第一列第二行的值。The value of the first row and second column of this Matrix. 預設值為 0。The default value is 0.


下列範例示範如何將兩個 Matrix 結構相乘,以及如何 Matrix 在宣告和結構之後,將值指派給。The following example shows how to multiply two Matrix structures and how to assign values to a Matrix when it is declared, and after the structure is declared.

private void multiplicationExample()

    Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
    Matrix matrix2 = new Matrix(2, 4, 6, 8, 10, 12);
    // matrixResult is equal to (70,100,150,220,240,352) 
    Matrix matrixResult = Matrix.Multiply(matrix1, matrix2);
    // matrixResult2 is also
    // equal to (70,100,150,220,240,352) 
    Matrix matrixResult2 = matrix1 * matrix2;
