[ITK] [ITK-users] eigen vectors in SymmetricEigenAnalysis

[samah]

hi ITK users,

When eigen values are ordered using SetOrderEigenMagnitudes ( |lambda_1| <
|lambda_2| < ..... ), are eigen vectors olso ordered ? so the first row of
the eigen vectors matrix is the eigen vector of lambda_1.

Here is the code :
typedef itk::SymmetricEigenAnalysis<
                   MatrixType,
                   VectorType,
                   MatrixType > SymmetricEigenAnalysisType;

SymmetricEigenAnalysisType   symmetricEigenSystem(3);
SymmetricEigenAnalysisType.SetOrderEigenMagnitudes( true ); 
symmetricEigenSystem.ComputeEigenValuesAndVectors
                     ( YourMatrix, eigenValues, eigenVectors );

Best regards,
