# Matrix.M12 Property

## Definition

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``

#### Property Value

Double

The value of the first row and second column of this Matrix. The default value is 0.

## Examples

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;
}
``````
