# Matrix.Append(Matrix) Method

## Definition

Appends the specified Matrix structure to this Matrix structure.

``````public:
void Append(System::Windows::Media::Matrix matrix);``````
``public void Append (System.Windows.Media.Matrix matrix);``
``member this.Append : System.Windows.Media.Matrix -> unit``
``Public Sub Append (matrix As Matrix)``

#### Parameters

matrix
Matrix

The Matrix structure to append to this Matrix structure.

## Examples

The following example shows how to append a Matrix structure to another Matrix structure.

``````private Matrix rotateAboutPointExample()
{

// Creating a Matrix structure.
Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);

// Rotate the matrix 90 degrees about the point (100,100).
// myMatrix becomes equal to (-10, 4, -20, 15, 170, 25).
myMatrix.RotateAt(90, 100, 100);

return myMatrix;
}
``````

## Remarks

This operation is the same as multiplying this Matrix structure by the parameter `matrix`. Matrix multiplication is not commutative, though, so this operation is not the same as multiplying the parameter `matrix` by this Matrix structure; that is, (this * `matrix`) is not the same as (`matrix` * this).
