Property Value

Type: System.Double
The value of the second row and first column of this Matrix. The default value is 0.

The following table shows the layout of a Matrix.

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;
