Matrix.Invert 方法

定義

反轉這個 Matrix 結構。Inverts this Matrix structure.

public:
 void Invert();
public void Invert ();
member this.Invert : unit -> unit
Public Sub Invert ()

例外狀況

Matrix 結構是不可以反轉的。The Matrix structure is not invertible.

範例

下列範例 Matrix 會檢查結構是否可反轉。The following example checks if a Matrix structure is invertible. 如果可以反轉,則 Matrix 結構會反轉。If it is invertible, the Matrix structure 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.");
    }
}
