# Matrix Constructor

Visual Studio 2010

Initializes a new instance of the Matrix structure.

Namespace:  System.Windows.Media
Assembly:  WindowsBase (in WindowsBase.dll)

## Syntax

```public Matrix(
double m11,
double m12,
double m21,
double m22,
double offsetX,
double offsetY
)
```

#### Parameters

m11
Type: System.Double
The new Matrix structure's M11 coefficient.
m12
Type: System.Double
The new Matrix structure's M12 coefficient.
m21
Type: System.Double
The new Matrix structure's M21 coefficient.
m22
Type: System.Double
The new Matrix structure's M22 coefficient.
offsetX
Type: System.Double
The new Matrix structure's OffsetX coefficient.
offsetY
Type: System.Double
The new Matrix structure's OffsetY coefficient.

## Examples

This example shows how to use a Matrix to transform Point and Vector objects.

```
private void transformExamples()
{

Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);

//
// Transform a point.
//
Point myPoint = new Point(15,25);

// pointResult is (475, 680).
Point pointResult = myMatrix.Transform(myPoint);

//
// Transform an array of points.
//
Point[] myPointArray = new Point[]
{new Point(15,25), new Point(30,35)};

// myPointArray[0] becomes (475, 680).
// myPointArray[1] becomes (700, 1030).
myMatrix.Transform(myPointArray);

//
// Transform a vector.
//
Vector myVector = new Vector(15,25);

// vectorResult becomes (450, 650).
Vector vectorResult = myMatrix.Transform(myVector);

//
// Transform an array of vectors.
//
Vector[] myVectorArray = new Vector[]
{new Vector(15, 25), new Vector(30,35)};

// myVectorArray[0] becomes (450, 650).
// myVectorArray[1] becomes (675, 1000).
myMatrix.Transform(myVectorArray);

}

```
