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

public bool HasInverse { get; }
You cannot set this property in XAML.

Property Value

Type: System.Boolean
true if the Matrix has an inverse; otherwise, false. The default is true.

The following example checks whether a Matrix is invertible. If it is invertible, the Matrix is inverted.

private Matrix inverseExample()
{

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

    // Checking if myMatrix is invertible. 
    if (myMatrix.HasInverse)
    {

        // Invert myMatrix. myMatrix is now  
        // equal to (-0.4, 0.2 , 0.3, -0.1, 1, -2) 
        myMatrix.Invert();

        // Return the inverted matrix. 
        return myMatrix;
    }
    else 
        throw new InvalidOperationException("The matrix is not invertible.");
