Member Function Documentation

template<class TMatrixElement, int VNumberOfRows> void itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GenerateData (   )  [protected]

Produces the eigen vectors and values.

template<class TMatrixElement, int VNumberOfRows> virtual const char* itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GetClassName (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::Object.

template<class TMatrixElement, int VNumberOfRows> EigenValueArrayType* itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GetEigenValues (   )  [inline]

returns the eigen values in an 1D array Definition at line 92 of file itkSymmetricEigenSystem.h. References HardConnectedComponentImageFilter::GenerateData().

template<class TMatrixElement, int VNumberOfRows> EigenVectorArrayType* itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GetEigenVectors (   )  [inline]

returns the eigen vectors in a 2D array Definition at line 88 of file itkSymmetricEigenSystem.h. References itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::EigenValueArrayType.

template<class TMatrixElement, int VNumberOfRows> MatrixType* itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GetMatrix (  void   )  [inline]

Set/Get the target matrix for the eigen analysis Definition at line 73 of file itkSymmetricEigenSystem.h. References itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::MatrixType.

template<class TMatrixElement, int VNumberOfRows> virtual bool itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::GetUseAbsoluteOrder (   )  [virtual]

Set/Get the absolute order flag. By setting this flag true, after the calculation of eigen vectors and values, if the absolute eigen value of eigen vector[j > i] is greater that of eigen vector[i], reorder the eigen vectors so that every absolute eigen values of eigen vector[j < i] is always greater than or equal to that of the eigen vectors[i]

template<class TMatrixElement, int VNumberOfRows> Pointer itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::New (   )  [static]

Method for creation through the object factory. Reimplemented from itk::Object.

template<class TMatrixElement, int VNumberOfRows> void itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::PrintSelf (  std::ostream &  os, Indent  indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::Object.

template<class TMatrixElement, int VNumberOfRows> virtual void itk::SymmetricEigenSystem< TMatrixElement, VNumberOfRows >::SetMatrix (  MatrixType *  _arg  )  [virtual]

Set/Get the target matrix for the eigen analysis
