Matrix.M12 属性

定义

获取或设置此 Matrix 结构中第一行与第二列相交处的值。Gets or sets the value of the first row and second column of this Matrix structure.

public:
 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

属性值

Matrix 中第一行与第二列相交处的值。The value of the first row and second column of this Matrix. 默认值为 0。The default value is 0.

示例

下面的示例演示如何对两个Matrix结构进行相乘, 以及如何在声明Matrix后以及在声明结构后将值赋值给。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;
    

}
