Matrix.HasInverse 屬性

定義

命名空間:
System.Windows.Media
組件:
WindowsBase.dll
組件:

取得值，這個值表示這個 Matrix 結構是否可以反轉。Gets a value that indicates whether this Matrix structure is invertible.

public:
 property bool HasInverse { bool get(); };
public bool HasInverse { get; }
member this.HasInverse : bool
Public ReadOnly Property HasInverse As Boolean

屬性值

Boolean

如果 Matrix 具有反轉則為 true，否則為 false。true if the Matrix has an inverse; otherwise, false. 預設為 true。The default is true.

範例

下列範例會檢查是否 Matrix 可反轉。The following example checks whether a Matrix is invertible. 如果可以反轉，則 Matrix 會反轉。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.");
    }
}
