# Matrix.Equality(Matrix, Matrix) Operator

## Definition

Determines whether the two specified Matrix structures are identical.

```
public:
static bool operator ==(System::Windows::Media::Matrix matrix1, System::Windows::Media::Matrix matrix2);
```

`public static bool operator == (System.Windows.Media.Matrix matrix1, System.Windows.Media.Matrix matrix2);`

`static member ( = ) : System.Windows.Media.Matrix * System.Windows.Media.Matrix -> bool`

`Public Shared Operator == (matrix1 As Matrix, matrix2 As Matrix) As Boolean`

#### Parameters

#### Returns

`true`

if `matrix1`

and `matrix2`

are identical; otherwise, `false`

.

## Examples

The following example shows how to check two Matrix structures for equality.

```
private void equalityExample()
{
Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
Matrix matrix2 = new Matrix(5, 10, 15, 20, 25, 30);
Boolean result;
// result is true.
result = (matrix1 == matrix2);
// result is false.
result = (matrix1 != matrix2);
}
```

## Remarks

Note

A Matrix stores its values as doubles. Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Double structures that are logically equal might fail.
